Oooohh! I'll be up for it! I can do the whole lot, PHP, AJAX, JavaScript/JQuery. Plus it's what I do for a living.
I've also developed alongside SMF, so just let me know whenever you need help with anything.
If you're making a homepage, I suppose it has its own domain/host? I'm not sure if freesmfhosting will allow you to just add on a homepage and start tinkering around with the code. Honestly, freesmfhosting is bad. You won't be integrating any of the SMF functions into the homepage whilst you're on this host to say the least.
I think we're just hosting the actual webpage somewhere else, then adding a link to it on evionet.
And I agree, freesmfhosting is awful and I wish there was a way we could export posts/members to an actual hosted version of SMF.
