Advice on starting up a burger/catering van

Hi,
I have been looking to start something like this for a while but never really got round to it. Having had a look round ive noticed some which are affordable. Mostly trailers but that shouldnt be a problem right? I was just wondering if any of you owned one or have done in the past. Where they any good? Good business venture? Good profit in it? I realise theres hygiene tests and trading licenses etc but are those hard to get? If i do get one it will be second hand, is there anything i should look out for when buying one?
And my main question is pitches. Im in Glasgow and those of you from up here will know the big car boot sales at the weekend. Ive also heard these types of things are sometimes ran by drug dealers and that trading near someone else could get you a sore face or worse. Is it really that seedy? Where does someone like myself go to make an honest living? I am near quite a few industrial sites, is it possible to go park up near them?

Please Help.

Thanks !

I didn't find the right solution from the internet.
