I am looking to customize an existing software that delivers and manages ads to web sites.
The software needs to have a concept of a publication, an advertiser account and an advertisement. It needs to have at least a rudimentary billing process.
A simplistic ad network, or banner exchange software, or domain parking software is the best match for what I'm looking for.
The preferred technology is .NET with SQL2005 backend.
Please reply only if you can sell us existing software with source code that can be salvaged for a similar project.
