Bootstrap/CSS3/HTML 5 Design Needed

Here are the requirements. Please let me know a cost and timeframe for this today as I will be making my decision later today (this is an urgent project). 1. Bootstrap, CSS3, HTML5 design deliverable 2. Current site is: [login to view URL] 3. Site needs to be updated to a more fresh, modern, fun and clean design. We're a party/event planning business so the site needs to be FUN! Current site looks a little homemade. We need you to keep the current site elements in place (like the reservation checking tool, carousel photos, and top navigation so our coder can hook the design to our database). These elements can be updated and refreshed though. We'd like to see nicer, more clean and modern buttons and form designs. We'd like you to show us a couple color scheme choices, we can choose 1 and then have you give us other color schemes later for different site skins. You may navigate through the site to see the various screens that are needed for design. Main page through checkout is needed. Only a few elements like form fields and pictures will change between those pages. Site should be designed with ecommerce best practices /conversion rate optimization principles in place. Please put the word FUN in your bid so I know you've read the above and understand our needs. Thanks!
