It is neccessary to point, that your task is not well defined. I need to know:
1. is the Access located on the same computer as ASP page (remote access to Access database is very slow and can lock your WEB server),
2. How many tables do you want to see on the page,
3. Is your page classic ASP or ASP.NET,
4. How much different EXCEL tables are you going to import.
I can agree with hourly rate at these conditions ($12/hour). Bid is calculated for 8 hours (1 day).
