After looking at the site, the title tags and your link dropped here I think your best bet would be to hire an
SEO company.
One of the first rules is keyword research, which it does not seem has been done.
Another is each page should have its own individual title tag if it is to perform well in the organic SERPs. Your clients site appears to be in a CMS with each pages primary keyword term is exactly the same

I would be willing to wager $1,000.00 there are no more than 20 searches a day for that term and that is probably being generous.
Another thing that seems to be missed is your target market is not likely going to click within the organic SERPs to find services your client offers.
Lastly there is an
SEO code of ethics, as well as methods of operating a business...... and I would wonder how you can take on an
SEO client??? if you do not have the knowledge to formulate proper
SEO title tags, much less all of the other points missed and pointed out by others here,
It is this exact practice which gives true
SEO's a bad name..............
Hate to be so blunt... but they are my honest thoughts.....
