I used a guy who came out to my yard, checked lorry over, fixed anything that needed fixing, booked MOT for us and took the lorry there and back - all i had to do was be there to give him keys! Will get the contact details from my dad and pm them to you later
Think we paid abot £150 all told for ours although only thing that needed fixing was the windscreen wash thingy!
Also CandR Days motors will do a pre-MOT check and MOT although maybe more expensive - not sure. Here's the link to his website http://www.candrday.co.uk/
