Stage 2 tuning in Essex

[jimber]

Hello, having owned my current 2L 2005 WRX for the past 6 years I have decided to spend some money getting it tuned, maybe to stage 2 depending on the cost.

Can anyone recommend a reputable mechanic in Essex to do this work?

Also, I want to improve the sound system, is it the head unit that's bad or the speakers?  I am not looking for mega bass just something with a bit more clarity and volume.

It needs a little bodywork also, wheel rebuild and a couple of little scuffs hear and there, ideally I would like somewhere I can drop it off, they do all the work and I can pick it up in a week or so.
