I need an email spider very cheap, something like Super Email Spider would be great. If you have that program or a similar one that you are the owner of the source code, let me know your price.
The program should be in .Net 1.1 or 2.0. Note* we want the source code. The extracting engine should be multithread (Thread save). With a Start/Pause and Stop button.
Also tell us how much you will charge to add a feature where the program will be able to collect more information then just emails (E.g. should be able to recognize American standard Address format and extract them from Yellow pages)
