SIMPLE DATA ENTRY

I have numerous Excel spreadsheets containing data with following columns: company name, sales revenue, estimated EBIT, number of employees, address, state, contact, industry, tel number, web address, name of bank, and comments. Some listings appear in more than one database. Some listings are incomplete eg no web address or phone number. I wish to consolidate all these into one large database, where I can easily search by sales revenue, EBIT, industry, state, no. of employees etc. Where possible the fields can be filled in through on-line research. You can do this work from home as a part time home based data entry work. I want to start as soon as possible.
