Van recovery from south 17 to Romsey, UK needed urgently!

Ok, so the lovely Renault Trafic van we bought in January in the UK has developed an unexpected and serious problem with its engine, and needs to be taken back for our garage to repair it under warranty!

Does anyone have any contacts in this area who might have a small/large transporter heading north anytime soon? Happy to pay/contribute if so: any thoughts/options welcome. (Having it repaired here is probably prohibitive - secondhand engine apparently needs locating and fitting. Hopefully the transporting won't be prohibitive as well!))
