Just emailed them with reference to their two day training course.
The conversation I had the other day went a little like this;
Client - We want a full site drain survey with mapping blah, blah, blah
Me - When for?
Client - As soon as possible!
Me - If I am honest we have concentrated only on surface drains and this is the weakest area of my business because I have spent no time on it and I am going to have to say that I cannot do the works at present!
Client - Thanks for your honesty
Me - I have a couple of numbers of other people who may be able to help
Client - You have been recommended, we have other people we can use!
I apologised and told them it would be dealt with as soon as possible
