I can fix this all up for you, add the new content, help edit what you already have etc. I'm an excellent writer, better than anyone else you'll find, I'd bet.
I see so many problems right off the bat. It's not terrible, but the design is boring. There are no parallax effects, no animations, and css customization is lacking. Your menu buttons open in a new tab, very annoying. You have a lot stuffed on the front page - it really looks to be too much text, not enough 'neat' on your front page. Your front page should be more brief, and direct people to other areas of your site. We can save and adjust the text, just somewhere else.
You have a fairly big job here, I know, by the time you're in Las Vegas that it would be very respectable. I have passion and pride. Just starting @ freelancer and need to build my my profile.
I feel i'd need 4 days just to redo what you have, then the rest of the time, add any extra content you have in mind. Let's get started asap, 2 weeks is not a lot of time to make this special. Feel free to ask me anything else.
