It's tricky to give an answer on this forum, mainly because the post would be very long, most likely boring and people picking one line out of context esp, if the text is not exactly how you thought it should read.
I don't think because someone can turnover £250 a day they are going to leave, and set up on their own, it's more complex than that, we all undervalue what we have done in building up a business - not everyone can do this, and how many people are in a position of being able to afford little to no income for a few months while finding customers and investing in a van and equipment ??
