maybe worth hanging on until they can do it then?
I know you are probably impatient, I am too but you can't blame them for putting corporate work first really, it is probably contract stuff and worth an annual amount rather than a one off job...
Can understand your frustration though, money to spend and nobody to do the work, crazy isn't it. A while back I wanted a bit of advice on fitted a double din to my missus MX-5, phoned 3/4 places and just like you they all said they just simply couldn't be bothered
