Hey there,
From your project description, I take it you already have a design, and simply want to make it responsive.
I'm a web developer with 7 years experience specializing in front end development, I do (clean, hand coded) HTML5, CSS, asynchronous javascript and responsive web design.
I'm used to working with other developers and understand that I don't write codes only for myself, thus the markup/codes I use should be easy enough for any developer to pick up and continue working on - something, in my experience, that goes a long way in terms of maintaining a website.
I prefer long-term work relationships (by long-term I mean repeat clients, not delayed work) as opposed to the typical freelancer mindset "finish quick and move on to next client", because I'm also looking for employers who value the quality of work they get, if we're on the same page, then perhaps I'm your guy for the job, so let's go discuss your project.
Best Regards,
Patrick
