But really, do you think small time publishers at first glance judge because of your website?.
They judge you on much more than just a website, but if the first impression of your website fails (which it does now), I hardly doubt if they're going to take a look at any of the other factors, given the amount of people that want to create games...
Selling games depends on a lot of factors. Like gaining the trust and confidence of others, the presentation of your game, the way you act... they all multiply. If one of these factors is 0%, the sale doesn't happen. If one of them is 10%, the resulting change will be at 10% of what it could've been without that factor. It doesn't add up, it multiplies, so you'll have to pay attention to every aspect of it.
So if you know your site is bad, improve it. It really needs improvement right now, as I can hardly see the goal of the site, I can't even find any of your projects or even information about it. Also, the links page does not contain links, or even copy-able text... no php required, just a little html knowledge and an eye for design could improve this greatly.
A tech demo is a good way of showing people what they can expect (or rather, a gameplay demo and preferrably a playable demo!) and a little text that emphasizes the strong points of your game are important things. How would you expect people to buy your game if they don't even know what it's going to give them? Be clear, be enthousiastic, and probably most important, provide them the actual fun you promised...
Not that I'm in this bussiness, but you pick up some stuff by reading and common sense, I think. Maybe this helps you some?
