I started out doing A LOT of free stuff. I still have those friends that I test out new stuff on for free. Until you know without a doubt you can deliver the product, in a way you want your name on it, don't charge.

I charge $100 for studio and $150 for location, BUT, I will give gift cards for $50 off sessions. If people are put off by the session fee, I can't get them in the door.

Your camera is not a handicap. You just learn how to use it to its fullest potential. If you want to shoot professional sports, it might be a handicap. If you want it to shoot portraits, there is no reason it should deter you. Lenses mean more than bodies and brands.
