You could take your cv to a few yards and ask if they need any casuals. It saves agency fees for them so there are some that use them I did it for it for a firm here and whats good is you can say yes or no and you dont owe them anything if you say no so wont feel bad like agencys tend to. If you get in with a place who use all class of vehicle and prove yourself an asset it could well be a foot in the door for a job on cat c or c+e later on but you have to do the leg work first
