I have had a look at you site and the homepage looks to be well laid out. I like the colour scheme, it is not too fussy or overdone as some sites are.
I hope you can fit all of your content in the space you have left for yourself. if not you may spoil your 'uncluttered' look.
The only constructive feedback I can give is the text on the button could be a size larger for me.
Overall though, I like it!
