I'm not Considering Working in the Catering Trailer?

Hi I'm considering buying a catering trailer, and read your thread which i thought was absolutely brilliant.

It was a very informative and exactly what i was looking for when i started my research.

I'm not considering working it myself I'm going to employ someone can you tell me how you did you go on declaring your earnings to the tax man.

I've been told you don't have to register for three months, also could you tell me roughly how much public liability insurance is the van.

I’ve been looking at is 12 ft by 6ft any info you think could help me i would be so grateful thanks, Fran.
