First thing I noticed is that your graphics are way too bulky. 75k?? each? This slows down your page dramatically at 56k connections and the graphics can stand a lot of compression and remain attractive. Don't let the browser resize those images. Use smaller images to begin with and it will look better and load faster.
I'm always an advocate for simplicity, so I like the clean look of your home page. I would replace the bright blue, and amateur-looking navigation buttons with something a little more professional looking. Three-state buttons are very nice - clean, but not static. I suggest you look at http://www.codebrain.com
for some great (and free) tools to spice up your site. Java applets are not difficult to install and give the appearance of competence in design.
Also detracting from a professional image is the slightly cropped logo image on all pages. (See the "m" on the right side.) This is your logo - on the web, it represents YOU and must be perfect.
I don't think you need a welcome or splash screen. Your homepage is very clear and unless you use the time that your splash is displayed, to begin pre-loading those big image files, there's no point to it.
Not to be harsh here, but on your "Virtual Hosting" page, you have a "more information" links, next to tiny titles which offer no information at all. Table this page and include a more descriptive title for each plan, perhaps with MB/GB and price, THEN the term "MORE information" will make sense. Check your code on this page. IE5 is returning a lot of errors.
Also, delete the link to Dedicated Servers, until that is available. Visitors hate following dead-end links to "under-construction" pages. Just include the news of "upcoming events and services" on your homepage and interested visitors will check back or contact you.
This site appears to be in the early stages of development, so I hope my comments won't be read as negative criticism. I take the time to look at sites objectively and comment as thoroughly and honestly as I can. I think with some jazzing up, it will be a good, stable site. Do try to find ways to personalize it - so it doesn't look just like 1,000 other web-hosting sites.
Best of luck,
