Your site has a professional feel to it, and a gaming feel to it which I quite like, even if black seems a little 'full tilt seedy'

I really like the idea, a guy I used to work with quit the job to concentrate on his 'rent a sunshower' business full time, which is pretty much what this venture amounts to.
there doesn't seem to be any mistakes in your site grammar and designwise. I would perhaps change the font and make the headings bigger, indent the paragraphs but those are minor issues.
Good luck!
