Is anyone or their DP/DH an HGV driver?

I need to get back to work. I've been out of the workplace for 14 years and need a job that I can fit round my 4 children.

I regularly drive my own 7.5t horse box and have done for the last 3 years. I enjoy driving and have started thinking about HGV/LGV driving as a job option. I realise I would need to undertake some costly training and probably another test to drive bigger vehicles but would be willing to do so and finance it myself if it was a viable means to an end.

If anyone has any info/experiences I'd be so grateful
