As the old saying goes 'one who does many things does none of them well' -- I wish my art was as good as yours (it's only like 75% of yours, honestly, ahaha, I super need to take time to practice drawing scenery). Coding is sadly more of a hobby for me, but there can often be a huge gap between 'making things work' and 'making things look nice'.
Luckily, once given art assets, a programmer should be able to do a lot, even if they wouldn't do it for themselves. Mockups are great, in that respect. Personally, I'm running myself really thin trying to be my own artist, designer, and developer. I've got the first two down, but the third... eh...
Just because I can make this:
...it doesn't mean I know how to integrate it with the actual navigation system to dynamically add/remove links through the admin control panel. What I can do is done with just CSS and a little bit of jQuery, but trying to integrate it with the navigation system in place? I don't even know where to begin, because HTML that provides the links is being rendered with object oriented PHP and I'd only just begun to grasp ordinary PHP last year - both of which are developer tools, not design tools. I don't know how to do both, so even I get held up and have to ask for help.
I wish you lots of luck finding help with your site, especially because you'll need to find people who understand object oriented PHP and can work with an existing framework - but in the meanwhile, we're all here for you! If you do snatch up people to work with you from other sites, send them here if they've got specific questions about the Mysidia framework. It'll be nice to see some new faces.
People may be tempted to say it'd be easier for them if they programmed it all from scratch for you, and I'm not sure which would be more costly - paying them to play nice with a framework that already exists or paying them to reinvent the wheel.
*That said*: try getting in touch with Hall of Famer, the guy who made this framework. He's fairly active and around on the forums! Maybe he'd be interested in directly helping you for a bit of money, but I'm not even sure he has a concept of a pricetag.
