Excel Import Application Project

Hi,
I need someone to create an application (but i would prefer a dll, that I can just hook up in my admin application) that validate a user specified excel file, and then import it to the database.
Fairly simple, but I got too much work, and convinced my boss that the right guys are in VBForums.
The catch is that this database tables, and views are created by a really inexperienced developer, that left me with his mess. So you might need a few days just figuring out what does what (I guess it's less than 10 tables and 5,6 views)

Let me know if interested, I will get what you need together over the week-end, and hopefully by early next week can give a quote to my boss.
Cheers
