I am a new freelance web developer/designer that is looking to build his portfolio up! I understand that you would like to have your wordpress site be build around a responsive design that models after a www.tuulavintage.com. I have taken a brief look at the site, and this is something that I can definitely help you with!
My skills include an advanced set in HTML5, CSS3, javascript and jQuery. Using these tools, I can most definitely meet and fulfill your requests.
What I would like to do, since I have no portfolio and am in need of building, is offer to you a mock up of a design layout. I will do this through photoshop and can have this delivered to you, to see if you do like my design work. This is entirely free.
If selected, I will begin work immediately on your site, starting from the mobile-design first. This is because with google, they will penalize sites that do not have such a mobile-friendly design. From here I will then build up the necessary code to make it seamless and cohesive on all platforms.
Please feel free to contact me if interested, I would love to hear from you! I will currently be available to contact from now until 8 am EST at my day/night job.
