Expenses for modeling all depend on your goals and budget, the expenses can be many or they can be minimal; it all depends on what your focus is.
Since there is a lot of competition and the economy is slow I would say to start off with minimal expenses, just enough to get your feet wet, just spend little amounts at a time, and if you start getting noticed and opportunities come your way then start spending more.
I always tell the models I work with to spend as little as possible and maybe more with work starts coming but we have to know how marketable we are and if we are in demand enough to justify extra amounts to be spent.
Hopefully this helps
