Thank you for your e-mail. Your honesty is much appreciated, as the wrong 'expert' could give me an answer that could cost me a lot more than I have already lost. I can wait until the end of Tuesday 19th May. If a suitable person cannot be found by then, please cancel the question and refund the fee.
Once again, thank you - you give me the confidence to use the service again.
