Hello,
We are a team with best developer and we can handle this job.
I am the project manager of our team and I have 5 years of experience in Website development using PHP, HTMl, CSS, JS, JQuery and also on CMS tools like WordPress, Joomla, CakePHP.
Since you need a website where you can update media/content easily, WordPress will be best for your use. With it you can make updates t the site, change menu, change page content, change media etc very easily from Backend. WordPress doesn't require any special cost but will run simply on simple web hosting, so you don't need to pay any monthly fee.
To check our portfolio, I would request you to check my freelancer profile reviews

Thanks and best
Akash
