I don`t want to rain on anyones parade, Gentlemen, but.....
The only thing these people understand is the threat of physical violence!
I work in the building trade, and come across this type of person all of the time, they fob you off with excuse after excuse until they get pissed off with your persistence.
Then they don`t even bother to reply to phone calls, e-mails etc.
I think you can kiss your money goodbye, I`m sorry to sound so negative, but this is my gut feeling about this.
Although this is only my two pence worth!
Cheers
Steve
