Wheel builder London? Bought a new bike and rode it for a week. Unfortunately the spokes loosend until it was unrideable. No idea how this came about but it looks like I need someone to rebuilt the wheel.

Does anyone know of a good wheel builder in East London or London in general? I need a wheel rebuilt and I thought I might just go with the best guy for the job!

edit: this is a Dutchie Dapper 3-Speed I bought four months old from someone who couldn't handle the size of the bike.
The wheel that finally worked for me is a Mavic A719 with Sapim Strong spokes and a spoke freeze as well as the thickest Schwalbe Marathon Plus tyre they could fit on the wheel. It was built by Mamachari Bikes in Dalston, London. I've been having no problems with it since a few months now.
