How Much Does a Private Investigator Cost in Chicago?

A Straight Answer About Cost

The first question most people ask me is also the one many investigators dodge: what is this going to cost? I understand the hesitation behind it. You are often dealing with something stressful, you have never hired an investigator before, and you have no idea whether you are looking at a few hundred dollars or several thousand. So let me be direct and give you real numbers, along with the reasons behind them.

Supreme Investigations is a licensed Chicago agency, and every engagement is quoted in writing before any work begins. There are no surprise mileage charges, toll fees, or report fees added after the fact. You will know what you are paying for and roughly what it will cost before you commit a dollar.

What the Core Services Cost

Manned or covert surveillance is billed at $200 per hour with a six-hour minimum, which comes to $1,200 for a standard day. That time is billed door to door, and mileage is already included, so you are not watching a meter for travel or getting an itemized gas charge later. The six-hour minimum exists because meaningful surveillance takes time; a subject's pattern rarely reveals itself in an hour.

Process serving is $225 for a standard subject. For a hard-to-serve subject, the fee is $650, which covers up to roughly six hours of attempt time including travel. Locates, skip tracing, and background checks start at $650. If you need unmanned surveillance, meaning a covert camera deployment rather than an investigator on site, that is a flat $2,000 for a five-day deployment. These are the figures the work is built on, and I quote them plainly.

What Actually Drives the Price

Cost tracks effort, distance, and difficulty. Surveillance is the clearest example: a subject who stays close to home for predictable hours takes less time to document than one who travels across the region on an irregular schedule, so the number of hours you need is the main variable. The written quote reflects an honest estimate of that, not a lowball figure meant to get you in the door.

Process serving is similar. A standard subject at a known address is straightforward, which is why it costs what it does. A subject who is evading service, works odd hours, or lives behind a controlled entrance takes many more attempts and more travel, which is what the hard-to-serve rate accounts for. Locates and background work start at $650 because the depth varies widely; confirming a current address is one thing, while piecing together a thorough background across multiple counties is another. When a case genuinely calls for more, I tell you before I do it, not after.

Why Written, Flat Quotes Protect You

The reason I put everything in writing is simple: it keeps both of us honest and removes the anxiety from the relationship. When you have a written quote with mileage and reasonable travel already included, you are not exposed to the open-ended billing that gives this industry a bad name. You can make a clear-headed decision about whether the information is worth the cost, which is exactly the decision you should be making.

Flat and all-in pricing also protects the quality of the work. When I am not nickel-and-diming travel or report preparation, there is no incentive to cut a day short or skimp on documentation. You get complete, time-stamped, court-admissible reporting as part of the service, because that is the product, not an add-on. I handle the work personally and never outsource it, so the person quoting the job is the person doing it.

Getting an Accurate Quote for Your Situation

A good quote starts with a short, honest conversation about what you are trying to accomplish. Sometimes people come to me certain they need five days of surveillance when a single well-planned day, or even a records-based locate, would answer their question for far less. Part of my job is to point that out rather than sell you the most expensive option. If a matter touches a legal case, I will also suggest you coordinate with your attorney, since that often shapes exactly what evidence is worth gathering.

Pricing should never be the mysterious part of hiring an investigator. If you are in Chicago, Cook County, DuPage County, or anywhere in Chicagoland and you want a clear, written estimate for your situation, reach out to Supreme Investigations. We can talk through what you need, and I will tell you honestly what it takes and what it costs.
