Hello Bob and Welcome..
FL is a tough state when it comes to PI work.. the pay is not bad if you can find a good company. (Interns would most likely start out in the $13 - $16 /hr at best, until you have your Full C license then you might be looking at anywhere from $16 to $25 an hour + expenses etc..but the pay scale you get all comes with the experience you bring to the table, so dont be discouraged or insulted when some companies may offer you a welfare type pay scale cause that is what happens here in FL, especially someone new with no experience yet. This new class training only started up a few years ago and pretty much is new to me as I never had to take this class. The only way I would need to take this class is if I let my license expire and then would need to jump through hoops to get it back so that wont be happening.. there are horror stories in any field and in the PI field they are present too.. I have heard of PI companies here in Miami "charging" you $500 a year for your internship hours so they will sign off on your hours for the state which is illegal to do FYI.. these are not the reputable companies you want to work for.. I know people pay this as they are desperate to get sponsored but this may only teach you the wrong workings of what a true investigator can learn & earn in the long run.
I would contact the PI companies in your area and inquire if they are hiring and be honest and up front.. you might get lucky where a company might wanna take you on and "Mold" you to their wants and needs as an Investigator.. I would also say to you that having the proper equipment for this job prior to applying is a must, as alot of companies do not supply you with this equipment although there are some that do.. Camcorder 200X Zoom (w/ NightVision)..Digital Camera..(35 MM Camera with Zoom Lenses).. Tape Recorder.. Binoculars (10x50 or better)..Cell phone .. Lap Top (w/mobile internet)..fax machine at home and the ability or knowledge to upload videos in an email after doing a case, along with a good detailed report of your investigation so the company may forward all this info to their client(s)...a good running auto (as you most likely will be sitting for hours and hours in your car doing insurance fraud claims like workers comp / and injury - accident claims where people are saying they are injured trying to cash in on a payday with fake injuries as they play basketball with their kids on Sunday at the park or go shopping at home depot and are lifting huge pieces of wood into their vehicles all the while you filming them and following them around their entire day.. (Now as far as Tinted Wiindows go for FL.. until you get your CC or C license make sure your tint on your vehicle is not too "blacked out" as you would not want any tickets for tint too dark by a bored cop out there
.. after you obtain your license you may legally black out all your windows and even tint your front windshield as well, as PI's in FL we are exempt from the window tint law in section 316.29545 of the FL Statutes. Your windows can be so tinted as a PI that you can flip people off ..drive naked and not one person would even be able to see inside the vehicle..front..back ..or sides.. 
but that will come after you get into the business..but all that I mentioned above will be needed eventually if this is your path you choose.But the one thing that is required right now by you is.. Patience.. in this economy it is not easy to find new work. Especially being brand new in this area.. but Dont give up if this is what you want to do..
Best of Luck to ya ! I hope you find what you are looking for..!
