you will need a Transit size van, dont buy small,you will need to upgrade and of course loose on your iniatial purchase, as with the other responses, the most important thing to do is get some training, 2 full days will be a good foundation to start with, and i would say a good start up budget would be in the region of £25k, dont forget you will need a lot more than just a machine, insurance, printing, add cost,s and so on, good luck
