Windows Platform Desktop Application Developer

For an upcoming project, we are looking for a good Microsoft Windows platform freelance developer to assist in the building of desktop applications. You must have a proven track record in this field. The proposed software application will interact extensively with web-based content, pushing and pulling it as needed. A very secure transmit mechanism will need to be developed along with relevant intelligent local caching and buffering for when web access is not available. Although the start-time is soon, the project time-frame will probably be inside the XP / Vista migration period so freelancers who are experimenting with the Vista betas and related API frameworks, and like longer term projects are preferred. Please reply with examples of past work, qualifications, rates, etc. You must be UK-based. No agencies.
