Hello,
My name is Brett Walker and on behalf of Cydia Solutions, I would like to thank you for this opportunity. I have read over your requirement and I am confident that I can provide you with a program that does exactly what your looking for. Of course I will need a little more detail on what letter and numbers you are looking for and how you want them called, but I can help you with ease. Honestly I might have bid a little on the high side, but I am not sure how extensive of an application you would like. Please feel free to message me any time. I look forward to possibly working with you in the future.
Thank you,
Brett Walker
