I have created other SEO tools for myself, and to give/sell for my own business. I am a professional internet marketer, and such tools as this come in handy. For my own use, I have created a vBulletin profile creator, wordpress blog commenter, link wheel creator with article spinning, proxy support.. multithreading, ect.
I said 10 days in my bid to ensure I have ample amount of time to complete. I request majority of the money up front, due to having to do quite a bit of work up front with no guarantee I will be paid. I am taking time out of my own personal work and business, and I am not going to risk wasting hours of time without getting paid.
The software will be created in Visual Basic 2010 .NET or C#, depends on what mood I'm in.
Your software will have proxy support, multithreading, captcha support.. whatever you need.
