Help!!

Hello,
I have worked in banking for 13 years and in 2013 began studying AAT levels 2&3 which I completed December 2014. I have since had a baby and returned to work part time but I would like to put my diploma to use and eventually work as a self employed bookkeeper from home. I loved studying and enjoyed taking my exams, I know I will be good at bookkeeping but I don't know where to start in terms of gaining some practical work experience. I am happy to do voluntary work around my job to gain some experience but where is the best place to start and how? I am very keen just need pointing in the right direction!
Thanks
