Hi Anya,
Great idea to start off on C4S, they already have the platform anyway, so it will save You a ton of hassle and headache of getting Your own site going.
You might also want to have a look at iwantclips.com/
The site is a lot "cleaner" in terms of design and functionality and they also have better payout rates for You
The easiest way to upload an image and post it here is to go to pixxxels.org/ upload a photo and then paste the URL in a message here.
(Also see the "Tips, Tricks and Tools" link above in the menu)
It's great to read that You have taken back control of Your life, i'm really happy for You!
Take care, enjoy life and all the best with Your new endeavours!
