Correct C# and vb.net programmes

Hello I have done a program on C# and .net and the program has some errors and I want some expert to correct the same. The main draw back is that - the output is very less. It is a image processing program, which edit the images by cropping, removing background, tilting and rotating and few more functions. Actually we have developed the program and it is working fine but the output is not more than 2 images per minute where as we require a output of 40 images per minute, at least 30 images per minute. So if any body could help us in this regard. Please let me know. Your job would be to correct the program and to teach me, where we have to correct our self. I have around 2 to 3 similar programs and I offer $30 each. Please let me know your interest. Send me your samples, so i could have a better idea of you. Regards
