Terms and conditions for the big cartel - a jewellery site

I need terms and conditions, delivery and returns, jewellery care possibly one or two other very short pieces of information worked upon.
I am having a site developed for the big cartel. The site is selling jewellery and i need the legal aspects developed.
I have information which can be used as a guide but it is protected by copyright and therefore needs rewording to avoid major problems!
If you think you can do this, please get in contact.

Thanks very much
Fran
