These are just a few options to consider, you may have a different view or mor to add.
The website is over due for facelift and this is perhaps the opportunity to do this.
I do like the No:5 Header (we can do the footer to suit any of the above)
But it would look much better if we could have the text on the new logo in white, even if it is just for the web version, which shouldn’t be a major problem.
