do a weekend course or 5 day course and see if its still what u want, if yes u can try get
in with a plasterer as a labourer which is a good basis and maybe go onto
city and guilds which i just completed,
good few years experince as a labourer with a long course is a good foundation to start with...
I started off as a labourer for my mate, pulling down lath & plaster ceilings, knocking up, cleaning his poxy van all the time etc
then i did a course and im now slowly getting into it now... I am also in sales... in a builders merchant so i get talking to customers
and the odd time i get a ceiling or wall or a bit of bonding etc, but its all experience......
good luck
