Can anyone point me in the right direction of an agent that helps people get their bike registered?

I've got a used bike I want to buy located in Gongshu district, already has a plate. It's fully road legal and has all the documentation, I need the help of someone who knows the right people and knows how to get things done to help me transport the bike to a district where it can be registered, the annual safety inspection needs to be done, the bike needs putting into my name, and the mandatory insurance for the year needs paying.

My Chinese isn't that great so someone that can speak a little English preferred.

Obviously I would pay for this service, just to be clear.
