Affiliate Center Lead Upload from .csv

We have a web site which we use to generate leads for our products. This website includes an affiliate center which allows our advertising partners to check campaign statistics which are generated as they send lead traffic to our site through unique links. However, some of our advertising partners send leads to us by emailing a list of leads in csv format. We need a script which will allow advertisers who are logged in to the affiliate center to upload the data in these csv files to a corresonding table in our MSSQL database. Our affiliate center is scripted using ASP VBScript with an MSSQL database. However, we will consider PHP, or .NET script. We require a working demo before payement will be made. The csv file will contain approximately 20 fields. More details about those fields, together with a SQL statement to duplicate the table into which lead should be posted, will be provided upon award of the project
