My wife is just (nearly) finishing up the building of a nice house up in Issan. She's the general contractor and it will be finished in about 3 months from tear down of the old house to a move-in ready new western equipped home of excellent quality. It took me three years to do that in Hua Hin... of course she is going to go 100% over budget...
But, the point is that other than designing the floor plan on my computer, she went there and spent 10 hours a day 6 days a week on site for three months and got the job done with only a little input and advice from me via photos, email, and phone. She has the confidence to do anything and tackle any job small or large (she single handedly repainted our previous 500+ sq. mt. home inside WITH A BRUSH).
Although I have to watch the financials closely as she still seems to think money grows on trees, there's nothing I wouldn't trust or depend on her to do except handle the credit cards or check book and that's not because she would unduly appropriate any money, she just still doesn't understand the concept of how hard it is to accumulate.
