let down by staircase fitter...

[Post and beam]

My staircase fitter was due to start this week. He has cried off for at least a month. I need an alternative and am struggling. Of course i run the risk of anyone available at short notice being suspect. But this cant always be true. I hope.  If anyone can recommend a tradesperson near north herts familiar with David Smith staircases i would be very grateful. Yes i have vontacted them directly.
