382486 Database Support Partner

I need someone to provide support for an internal database. Its simple work for a pro it'll just be for when our internal guys find a problem with 3rd part data that causes a linked table to mismatch, of possibly to add new standard linked tables into existing query formats. the database is very low on interface with users. It links to 70 or so sales tables provided by 3rd parties, and 4 cost files. These are standardised and indexed (and index needs to be created out of a text field using instr type function). Then all the data is assemble to produc a large profit report of all lines of data. This is aggregated into a few reports and excel dumps. So pretty basic (its written by a non programmer so just using drag and drop available in access). I envisage this to be either on a retainer to establish a guaranteed response time to issues, with some rate over and a above a couple of hours a month covered by the retainer.
