if you have nice legs, hands feet, skin and a personality there is no reason why you can't model. You just need to focus on your photos and marketing yourself in ways that WILL get you ahead. Skip the amateur modeling and go right for the commercial print modeling agencies or grab your bootstraps and approach photographers that shoot print work and with magazines and ask for a test, sometimes forking out a few hundred is worth it if the photographer is good. Then make yourself a comp card, www.compcard.com for decent price. Sometimes you have to invest before you get paid!
You might not walk the catwalk or flaunt Vogue each month, but you can still model if you focus on print work, body part modeling, shoe models are a size 6! Most short girls are a size 6!
