Not sure if anyone can help me here...

I have set up a business to provide services to mobile phones and shortly after landing a deal to be on the approved list of a major client , my developer decided to go walkabout. So I'm looking for a developer to work alongside me to work on MMS SMS .net and all related programmes, if no one here can do it can anyone point me in the direction of somewhere I may be able to find someone? Based in Yorkshire so ideally someone from round here , although could be done from anywhere.
