If you spend $$ learn photographic basics, you'll be better off than after 100 "model" shoots.
If you can post up such shots, you should have the "face" to attend basic lessons. I'm sure there's no shortage of people who'll recommend you SLCC immediately.
One problem with alot of photographers here: After they pick up dSLR, they think no face to go for basic lessons to learn about exposure, that they aim point shoot they'll get "good" photos. Best of all, some start offering their services as a freelance photographer.
IMHO, YLSX => Personally I get the feel that you're putting too much emphasis on equipment, that by getting the equipment you will be able to get better shots. I believe many people has gotten better images with the same equipment as you have. should stop wasting money on photoshoots, and actually attend lessons to learn the basics. It doesn't mean that pick up better equipment = become pro.
