Okay, I can relate to what you're saying Khagga. Have you thought about approaching your local Video Making Club?
The IAC, Institute of Amateur Cinematographers have a list of filmmaking clubs.

It might be worth approaching your local club and offering them five hundred quid for their funds in exchange for a video. I'm normally against getting amateurs to do professional work but I guess that this is one of those occasions where either amateurs do it, or it won't get done at all. I will echo what Marc said though, don't go for a cheap professional. Someone who charges less than a grand for a wedding ain't gonna be much good.
