Hello,
I have over 20 years experience in development, including many years of WordPress and other CMS experience.
I suggest to use WordPress, a simple yet powerful framework as CMS, which will allow you later to make changes your self without any limitations.
My offer includes basic installation and configurations of WordPress using your own domain name and hosting, this may include configuration of responsive free theme. For your own design, I have to see the design, if does not have much complications and can be configured within this theme, then we are on as above, if not, I may need to ask for a little more money to cover the changes.
The basic installation, would mean installing a free theme, configuring it, install necessary plugins to get the functionality you need.
Please let me know more about what you want to do in this website.
Best regards,
Submission of 26-9-2014
