How Much Does It Cost to Hire A Private Investigator in Naples, FL?

Well, the exact cost of a private investigation job is dependent on several factors. These include the nature and scope of the investigation, the number of private detectives needed and the time frame within which the investigation should have been concluded.

In order to know how much your case will cost, you’ll have to discuss that directly with our private investigator. Here, you’ll give us all the details and facts about the matter you want investigated and we will then generate an exact quote for you.

How Discreet Is It to Hire A Private Investigator?

Discretion is one of the most important aspects in private investigation. And as an experienced private investigator firm FL, we are always very discreet with all the information we gather from you. We are even careful when choosing the venue in which our detectives will meet with you for initial case discussions, ongoing updates and/or conclusive reports.

Types of Cases We Investigate

Our firm has a team of special insurance claims investigators that can help you unearth important info on possible fraud relating, but not limited to the following:

  • Worker’s Compensation
  • Car Accidents
  • Staged Home Fires
  • Storm Fraud
  • Faked Fires

  1. Domestic/ Personal

Custody Cases

Most child custody cases are often heated with both sides leveling allegations against each other. And it’s only an objective private investigator that can help put matters into perspective. Among the key aspects we investigate are the child’s well being and treatment.

Our private detectives deeply understand child custody investigations and can help reveal crucial information to a client in many ways. They can interview witnesses (neighbors, counselors etc.) for claims of poor treatment, do asset searches where a parent is accused of shirking their financial responsibilities and/or do background checks on the other parent for criminal records.

Infidelity or Cheating Spouse

If you have reason to suspect your partner or spouse is cheating, Case Closed Investigations can help you know whether it is true or not. We use many ways including surveillance, hidden cameras, online dating and social media profiles search and more to uncover infidelity. We’ll discreetly provide all the answers you need about your spouse on time, so you can have peace of mind or make the necessary decision as early as possible.


If you want to keep an eye on your suddenly suspicious partner or child or an employee suspected to be involved in fraud, our firm can help get you out by performing surveillance. We’ll combine the use of electronic, photographic, video/audio recording and other electronic equipment to secure solid evidence that will help you know the truth as it is and take legal action, if need be.

Due Diligence

Before doing a legal transaction like a company merger or purchase with another company, analyzing it comprehensively to establish its credibility is very critical. When doing such due diligence, you need a hand from an experienced private investigator.

With the massive experience we have in handling such cases, we can help dig and examine such important info as following:

  • Company history/overview
  • Management
  • Financial costs, revenues and structure
  • Employees
  • Marketing audits
  • Liabilities and equity
  • Production and reconciliation audits

Note: When doing due diligence, we can employ many tactics including forensic accounting investigations, surveillance, background checks, asset searches, mystery shopping and more.

Corporate Investigations

Do you suspect any wrongdoing by your company management, employees or business partner and want to uncover the truth? A private investigator can give you all the answers you need. It doesn’t matter whether you’re investigating a business partner who seems illegitimate, an employee who’s stealing from the company or a team of management that’s involved in fraud and embezzlement. We can simply handle them all.
