Dear,
I'm interested to learn more about your project and, for start, I would be thankful if you could answer on a few questions:
* How many pages site have?
* What type of hosting service are you using and do you have ssh or ftp access?
* Are needed changes just those you listed or there would be some more?
* Do you already have some content for the site (text, images etc.)
* What is time limit for finishing this project?
I graduated in New computer technologies (School of Electrical Engineering and Computer Science of Applied Studies) and I've been working in IT field for over 18 years (PC Assembly Technician, VOIP administrator, System/Network Administrator, Intranet projects), and last 8 years as a web developer (mostly using WordPress as a platform). I mostly worked with clients from the UK and USA covering different aspects of the web stack.
Regards,
Ivan
