Thanks maxzor and dedom, I'll research into the docs that you've mentioned. maxzor, I got in touch with Transmed, I can see their quite reputable but their actually asking for about 2.5 dollars a graft which in my case would go well beyond 15000 dollars. I would definately look more into it if they were to do it for 1 euro graft- is that a recent price your quoting?
