Front page / change

We have a website built already. We like the design and dont want it changed. What we require changed is the angle to which we are currently getting work.

For example. We are a drainage company. We have been (for the last year) been dealing with blocked sinks and toilets - our website reflects that kind of work. What we want to do is keep that as one of the things we do BUT change the narrative slightly and the pictures to reflect

Excavations
Soakaways
New chambers (plastic or brick)
Pump pits
Blockages

Excavations being the main angle that the website shows. I have already zipped up loads of pictures, and a few websites that can be referred to to copy text and our understand what we are talking about.
We had another website designer doing the work and we like what work he has done, but he has messed us around for the last 2 months saying that he would update the front page and then disappeared. We had been awaiting around for him to do the work as we liked his work, but we have decided to let him go and find someone else that can do what we need.

I have the information ready on an email and can send it across....
