Class 1 - New Driver Start - Northern Ireland

Hi guys, I’m based in Belfast, if there are some local guys can help me.

I have just passed my C+E test, with 4 months class 2 driving. I’m looking for a company to start with to get my foot in the door, I’m willing to do weekend work to gain experience perhaps 2 days per month voluntarily if need be.

Does anybody know the best firms that would be most likely to take a new driver?

Thanks
Dominic
