Hello,
Whilst I have no experience of having had a book published by this organization, I can vouch for the quality, distribution and prices of their products. Check out the site:

I suggest you have a chat with Peter Kassak (a member of TOCH). One of his books, 'Gardening by Midnight' (co-authored with David Gunby), was recently handled by Lulu.
