A lot of the parcel companies (TNT, DHL, FedEx, etc.) seem to use subbies an awful lot. Mark Thompsons yellow lorries seem to be quite popular, but I have no idea what they’re like to work for. Might be worthwhile thinking outside the box a little, but be aware, in my limited experience in that field, they do have an expectation that the driver wont dawdle.
As far as reversing goes, everyone struggles at first (and some of us still do! 
), but very very soon, it’ll click and all make sense.
