Hamann PG4 Refurb

After a decade in storage I finally got round to getting my Hamann PG4 split rim alloys refurbished.
Unfortunately this took a lot longer than planned. The wheels were dropped off at 'said company' last August and I finally managed to prize the 4th wheel off 'said company' today ........ a long story of kicking the can down the road.
Unfortunately 3 of the tyres are not holding air and I'll be dammed if I'm going back to 'said company' in order to rectify.
Does anyone know of a refurb company that would look at split (x3) rims in order to make this old man happy.
