WordPress and SEO for my website

I need a designer/ developer who specialises in website WordPress and SEO. I have a Yahoo small business basics builder website that is already built, which I would like to improve and take further by incorporating WordPress and SEO.

The website address is https://www.iifs.co.uk/index.html

The website is a simple basic website for micro-business in advisory/consultancy services that do not require e-commerce or other complex features. The key issue I would like to resolve is that the website does not appear on Google search and does not have WordPress.

Please provide your detailed proposal to address the requirement to ensure the website incorporates WordPress and becomes visible on search engines in the most cost-effective way and your quote to deliver this job.
