Hi can anyone point me in the right direction of somewhere that can rebuild a turbo on a astra vxr i suspect oil seals are leaking

Somewhere in north west perferably manchester area that can remove the turbo and refit if i take the car to them as i dont trust myself doing it right are they easy to refit ?

What sort of price would i be looking at as you can get a new turbo for around the £450-£500 mark

Dont worry i know its a Vauxhall but once turbo is sorted i can get shut of it and get back in a RS
