Desperate for help - inspection/service

I really need to find someone who can take a look at my MH

I'm living and working overseas, with our van in commercial storage in UK (Cardiff). We haven't seen or touched her since June 2019 and now because of coronavirus it's highly improbable we'll get back to UK before early 2021.

I am desperately worried that the van will be completely seized up and batteries/tyres wrecked by the time I get to her again.

I'm trying to find someone who can inspect the van externally and mechanically - not the internals and coachwork. Check if the batteries still have charge from solar, pump up the tyres, see if it moves freely, identify any obvious problems and provide recommendations.

Please any recommendations for service agents in the area. Or alternatively I am prepared to pay a private commission.
