I've spoken to some Sussex geeks recently, and it seems that finding a freelancer or contractor for a short job, a few days or a couple of weeks, is a bit hit-and-miss. Recruitment sites tend to focus on permanent jobs and contracts, usually measured in months. There are some resources, such as the Brighton Farm, which lists members' skills and has weekly meetings, but someone suggested to me that a small job board would be useful, targeted in the local area.
So I've set one up called Sussex Geek Jobs. If you want to hire a local professional for a short job (under a couple of months, or maybe a few hours per month), then post your requirements there. There's a nominal fee of a tenner, which is mainly to prevent spammers, thus saving me moderation time. The ads are shown for 30 days.
If you're looking for a quick job, then check out the job board, and hopefully there'll be something suitable.
