Hi tezmac & welcome to TRF.
I’m pretty sure that a new member came on the horse racing forum and said that he was doing this with 10 grands worth of redundancy money, having previously tried paying for info from a number of sources.
He felt this was equally effective (indeed up to that point he was in profit) and free!
A number of members advised caution I seem to remember but I’m darned if I can remember the member or the thread title so can’t search for it for you.
Good luck & again welcome.
