UI / UX / Graphic Design required for Wordpress/Woocommerce/Buddypress website

We have a website upcoming in about 1-2 months. It's based on Wordpress/Woocommerce/Buddypress and uses Mindig theme as a base template. It will be heavily customized to achieve what we need. Coding and some generic graphic design is covered and in progress. We now need a UI/UX/Graphic designer to make the presentation more original and unique. What's included in the to do list is a simple Coming Soon one pager and almost every single page involved in the website (some pages will contain similar structure/layout and requires no redesign hence the word 'almost') You will be working with our lead developer and contribute your work accordingly. There will be predominantly rearranging the page layout, position the page elements, suggest font, graphics, effect and any user experience process. We will provide anything that requires reasonable purchase, such as the graphics. On top of that, we have some ideas of what the website should look or feel like. You just have to convert this concept and plus your own idea to reality. There wouldn't be too much of the get-your-hands-dirty job. What we aim for is originality and simplicity. Flat UI and easy to grasp UX is preferred. Our fixed price budget will cover the initial tasks as outlined above that needs starting rather immediately. We will also require you to work extra hours (hourly based) for any additional tasks involved such as a new function added which requires a new page. Any proposal without personalized information and relevance to the project will be ignored. Thanks for bidding.
