Access data manipulation

This has had to be re-advertised... I need a macro to manipulate data in an access database. I will send you a database sample to work on. There are 2 tasks the macro needs to perform: There is a field called assigned which is blank at the moment. I want the first 20% of all the records (there's typically about 2,000 records) (ordered by the record number field) to have the value 1 in the assigned field. The second 20% of records should have the value 2 3rd 20% value of 3 etc etc up to 5. Second part: There are 3 fields which need to be combined into a google search string. The 3 fields are "company name", "type of business" and "city". There is a "website" field. For only those records in which the website field is blank the website field needs to be filled with a string which is of the form [login to view URL];q=company+name+type+of+business+city&meta= Please only bid if you can do this within the time that you state. Thanks.
