Yahoo PPC Bid Management Tool Needed

Hi, I need a tool written to enable me to manage my PPC campaign keyword bidding. I'm only interested in Yahoo Panama & MS AdCenter initially, but I'd like the tool to be written in such a way as to allow other PPC search engines to be added at a later date. I've used Bid Maximizer - [login to view URL] - in the past, and I would require similar bid management functionality, but I do not need to be able to create and manage keywords, ads, etc. I need a solution that I can install on my dedicated windows server, preferable written in ASP with a web front-end, or in VB, with a MySQL database back-end. The sort of functionality that I need is; - Select & download existing campaign(s), - Keyword bid range & desired position setting, - Bidding Rules (Bid to position, Best value position in range, Bid Jamming, etc), - Scheduled keyword position monitoring and bid adjustment. - Multi-Region monitoring (US, UK, Canada, etc) The tool should function using the Yahoo Panama / MS AdCenter PPC APIs for setting bids and retrieving campaign details, and with the Yahoo / Microsoft search APIs for monitoring keyword positions. Ideally, the winning bidder should have worked with these APIs in the past and have a similar system already that can be demonstrated to me. Thanks! Dan
