Hmmm... have somewhat hijacked the thread :P Never actually checked the rules before; not sure I was intentionally trashing your advertisement, and I was under the impression we were meant to pass judgement on advertisements... apparently not
Anyway, I did get carried away in the discussion; I don't think anybody who would have considered your services would be put off by my rantings about an honourable internet, but I can see the point.
I shall edit the previous two comments (the first I will keep as my original critique) and bid you good luck with getting that profit margin up!
