Need homepage design for a crowdsourcing platform

We had posted a project earlier but it was a bit vague in requirements so we are reposting a more specific project. We need a really good designer to help redesign the home page for our website - [login to view URL] which is a fast growing crowdsourcing website. We are looking to create the design a bit more engaging, as well as more inviting. Current design and theme is a bit too dark. We will provide 3-4 reference sites that can be used as an example of the color scheme/ layout that we are looking for. Please provide a bit for redesign of the homepage. We have other needs as well (redesign of inside pages) as well as HTML/ CSS changes and banner ads. However, we will engage you for those needs via additional projects on vworker. Again, you must have extremely strong design skills and must be amonth the top rated freelancers on vworker.
