364683 Heavy Zen-Cart database work

I am in need of heavy Zen-Cart database work. I have two spreadsheets, one with 30,000 records and the other with about 1,000. The smaller spreadsheet contains the actual products, while the larger spreadsheet contains the categories, or possible "applications" for the 1,000 products. Need a programmer who can start RIGHT NOW, and who has SOLID experience with Zen-Cart and inserting these products into Zen-Cart. I am not looking for the cheapest, but the BEST. thanks
