I have done this as my only job for around 6 years now, as with any job, it has its ups and downs, its not for everyone.
The money is quite good,its pretty much full time wage for part time hours, however I must be honest, if I could find a normal run of the mill job, that paid the same amount of money, for the same amount of hours, I would pack in tomorrow.
A few years ago I wouldnt have changed jobs for the world, but one the SIA licencing came into play, it all went to shit, and now theres pretty much a shortage of decent lads, alot of the bigger companies now have to many positions, so are using muppets who've never worked a shift in there life. Not the sort of people who you want beside you in a kick off.
