I have just recently obtained a connection in London that is probably exactly what you are looking for. I do alot of networking across the world and have recently gave this contact information to a few interior designers who were thrilled with the availability of the concept. This company is very reputable and very well priced. Being an artist myself the work that I have seen is of the finest quality. They have access to 5o some artists around the world and can have your painting done in any style ,technique and medium. Based on your fabric clippings and your direction. I do not charge for helping people with this kind of information, I believe in givers gain and try to help as many as I can. Send me an email either through this forum or my blog at
