Have just nad a website created by a wonderful man... who has now disappeared - without a trace.? It is 99.5% done, but he has not added postage rates etc., and has not? done done the minor amendments I recently sent him? : colours of fonts need changing / fonts need chaning / photos need adding / photos need to be put on rotation / more photos need to be made available to customers...? he has given them only one to choose from?!?! This is EXTREMELY URGENT....? ? because he had almost finished last week, I had my car sign-written, and people are already using this site, which is making me look stupid, as it is inoperable.? They simply cannot complete their purchases.... Please ask if you need to know anything else....? I might be able to help??!? Andrea? ? ? ? ? ?
