Thanks to all that have replied to date. I understand what you all say but at the end of this my wife and daughter are my stumbling block. They have this vision of being famous and if it doesn't work out someone will have to take the blame. I will write down, and ask, all the questions I feel need to ask. And I will ask for a contract copy before we go to Bangkok and have a lawyer give it the once over first.
It's all a coincidence as I just purchased a new T-Shirt tuther day.
