Thank you.
If you have any questions please PM.
You must be sure you can solve the problem and quickly before you bid - this is the second time this has been posted. I think the other guy was a novice C# programmer and did not read the description properly.
You must actually understand what I wrote - British, American & Australian coders are preferred.
Please keep prices low.
