New self employed driver

Hi, sorry if this has been posted before but I’m looking for advice. I’m a self employed contractor looking for HGV experience, I have a rotational job which is my main source of income but I am looking at doing HGV work when I’m off contract or just quiet. What’s the best way to get a start ? Quite willing to be on a well reduced rate or go 2nd man just to gain experience to start with

Why would you drive for a well reduced rate ? This is a bad idea,Plenty of firms will pay you the same as all drivers ,Contact them ,Search for haulage companies in your area on google maps ,Then call them up .

If doing LGV driving as well as another job then be very aware of the EU regs weekly rest rules
