Thanks for the extension, prize increase and sealing the contest.
As per your question before a few days, design is totally different than development, design provides you with an image of how your page is expected to look like, while development is making it really work including form submissions, responsiveness and other things.
I do the work as a designer and developer, so I should be alble to deisgn your page and make it actually work.
So, even the $210 might not be enough for both, they are a good encouragement for the design, but not both the design and development.
I will submit my entry in a short time, then we could have a chat then I can make it completely functional.
