OK – so your key qualities are:
Lawyer – or – Attorney
Wants to earn $300,000 (or may be add another 0 as well)
Hmmmmmmmmmmmm – how about an office within the Busienss Travel magazine blog, collecting a one $ or one £ from every whinging whining or moaning expense account sales man or women.
If that made you rich in too short a space of time, how about a legal service specializing in travel related issues of an international nature. In this culture of everyone suing everyone else, you could offer a service bases proposition, whereby, you would cover the world in offering ‘PERSONAL’ serivce to those who have suffered from a bout of toy throwing withing the longhaul travel sector.
So, for the sales man who is moaning about the whinging kid in front, tell him how to sue the parents/guardian or airline (maybe all 3) for not only a disturbed nights sleep but also the consequential loss of that missed bonus becase he lost the sale.
For Mr perfect, whose dinner contained a soggy piece of meat, you could act for him in the courts and find somethig else to sue for.
I am sure you could be the typical legal man and go for the jugular each time
………..otherwise try being a fictional writer………..!
