Payment offered to get plugin working

Hi.
I cannot get the plugin to work.
I have tried on many occasions.
I will be pleased to pay a modest sum to someone who can get it working for me.
I will give my login details only to a known forum contributor.

The site is http://www.floshmeadowsselfbuild.com

Please help
