by all means il do it for you soin, but fully booked till middle of january.
but before you start letting others tamper with that rebuild 'take a tip from me' and let the people that built the engine sort it out as it should not be noisy, so they have not done it correctly in the first place.
if you now let someone else loose at it then you will invalidate any warranty they have given you, so if the worst happens and engine blows up then you have nowhere to go other than sort it out yourself!
