Very interesting.
I would suggest swapping the current structural aesthetic of "come in and look around" for the somewhat more widespread approach of having one or more calls to action and making the homepage fully sketch out the points you want to make.
FWIW, I say this out of pragmaticness. I don't mind the "welcome! browse!" approach myself, but it won't appeal to the demographic you're trying to reach: people who themselves are being paid to eat/sleep/dream modern web design.
Another thing I would recommend is using every single trick in the book to make the site fast. For example you could get ServiceWorkers caching everything for future visits (with maybe AppCache on top just because) and use the HTML5 history API so you can preload all the site text (say, in an XHR that fires after page load) and use that to make it feel like navigation is superhumanly fast.
TL;DR, use this as your playground to learn how to make sites load better. Voila, the site will be stupidly fast, and it will self-describe too, which is kind of cool. And you'll wind up with a bunch of knowledge you could use for consulting... and then you could use the site as the home base for that, which would be even cooler.
(I realize you just started this project, and that the above suggestions are in the "Rome wasn't built in a day" category)
