At 5'7" and 23 years old decent agency representation will be hard to find, even though you do have a nice 'agency friendly' look.
If you want to make money from modelling as an independent model then you will almost certainly have to start shooting nudes. I'd shoot some fashion nudes with you on a TF basis without question if you were interested, and plenty of other photographers would be happy to pay you for fashion and art nudes, or even glamour.
Making anything more than occasional beer money as a freelancer without getting naked though will be next to impossible.
