Hello there.
I think, you have a wrong conception about what you want.
If is true you have a fully functioning macros, translate this to VB.net or C#, require a re-coding. So, this is a Project with some qualities bigger than "just convert from excel into .exe"
If you send me your excel first, I can take a look into the code in order to give you a real budget and time. Take in mind that this kind of app, require a Database to store all the scrapped data. This could be Sql server or Microsoft Access.
Let me know and let's discuss....
