Kaleese, I would be wary about asking for too much specific advice, because everyone works differently, and has different boundaries, lifestyles, aims etc.
Aside from reading the (fantastic) general info on here, one thing I found useful was just looking at other escort's personal websites, particularly about their services and rates, but also any blogs in which they gave a bit more personal info, and perhaps some comments about how clients behaved.
You need to decide:
1. Where you are going work
2. When
3. What you would like to do and what you definitely won't do
4. And your rates
When you've got all that straight in your head, write an Adultwork profile as appropriate - draft it in Word first if it's easier to edit it that way. Remember some clients won't read much, so keep it simple, straightforward and brief. Then just have a few photos done and you're ready to go.
If you're going to work from home, you will probably need to buy extra towels, bedding, toiletries etc. and of course shedloads of condoms. If you'd can't afford this, you'll presumably have to start off doing out-calls only to get a bit of money behind you, and would just need a few outfits to begin with. And the condoms!
