Well even though you are an "eagles fan", welcome to the "Flames Board" (Bucs fan myself).
Anyway, pretty tough question since we don't know exactly what you are doing, so I will just give you some basic costs on doing a job.
On a job doing a basecoat/clearcoat with three parts (2 fenders and a tank), you will probably be looking at about $200-$300 in materials to do a paint/flame job (this of course, only if you use
quality materials. You should be able to rent a compressor, but it should definitely be filtered to make sure you don't get any moisture in the job.
You will also need a place to spray.
You will also need a spray gun (maybe 2 if you have to prime).
Lot's of variables, but hopefully this will help.
Pretty much worth it just to let someone else do it.
Most of my jobs run from about $850-$1550 if you need a quote, you can fill out the form
here . Be sure and mention the "Flames Board"
