Dfs/scs furniture delivery anyone done this work?

So Dfs and scs and quite a few other are all looking for drivers, I was thinking of attempting to contact them to try and place a truck? Has anyone done this sort of work that can tell me do they pay per delivery or a flat rate and roughly what it works out at I know it’s probably not going to be what I’m used to pulling in but I’m trying to not see anyone go out of work if I possibly can! It would also appear impossible to actually get hold of warehouse numbers anymore so any help with that would be greatly appreciated failing that I’ll have to take a trip down there! Thanks in advance
