Many congratulations on embarking on a new and exciting life journey. I wish you every happiness - and plenty of health & wealth to back it up!
I don't know what country you live in so it's difficult to understand whether you are talking about the sex industry or something more supportive of other transgender people or any other type of work. Here in Thailand Ladyboys are everywhere - Checkout Girls in Tescos, Travel Reps, Bank Clerks.. You name it.
Back in the UK there was a thriving industry supporting Ladyboys. Shoe & Clothing suppliers, make-up specialists, dedicated transgender nightclubs, hotels, bars, restaurants and even holiday companies. I guess what I'm saying is that one alternative could be to become a part of that "support network" that you are now looking for, so that you can help others like you in the future.
There is no doubt that being a sex-worker (in whatever form) will probably get you the most money quickly - and this is possibly most important for those contemplating surgery - but please take care of your sexual health.
Whatever you do, I wish you every success.
