Create an Access DB from 1100+ Excel worksheets

Hi,

We are a small private tutoring franchise business who, as well as providing tutoring services via our franchisees, also supply the associated materials to franchisees to supplement their tutoring (for both Maths and English).

We'd like to collate the order quantities by subject of the study material orders placed by franchisees with us. Attached is an example of a single file submitted by a franchisee to us for ordering. There are almost 1200 similar files to extract data from. There are 4 different versions of the file; only where additional subjects have been added or taken away during the last year or so have versions changed slightly (I will provide sheet unprotect passwords for the files in due course, but the attached file is already unprotected, fyi).

Note, we are interested in collating the information on the 'Maths' and 'English' tabs only. We need to sum rows 3, 14 and 70 across each subject column (so for Maths, NB / AS1 / AS2 etc etc are all different subjects).

So creating an Access DB of material 'sets' ordered (or perhaps two DB's - one per subject) is the project and ultimate deliverable. Please advise on your availability and a likely timescale for this.
