Great point James, when I read the first paragraph I was a little confused.
Excellent site, I don't know what else you want me to say.
I have had a very similar idea, you just never know if an idea like yours will take off.
I was going to pick on you for not using a Gallery plugin like
Lightbox, but you have and the effect is very impressive.
Though I would have a few more scenic images rather than people for a more dramatic affect.
Honestly though it's really hard to pick on your site as it is pretty damn good!
Love the header, navigation and the light clean color scheme. I also like how there is no advertisements on your site.
Considering the type of site it is, I don't think Ads will help it in any way.
Others might disagree.
Congratulations on a beautiful, clean and interesting site and an original online business idea.
Well Done 9 out of 10!
