My first though upon seeing your portfolio was howcome you didn’t choose: smugmug or photoshelter?
There are a whole series of reasons why you should use a real service like one of the above ranging from SEO, to ease of use to quality. But mainly they both cater to photographers specifically.
I actually just chose it because I didnt want to pay for one of the others. I pay for hosting through Intuit because I like the security ( I file my Taxes through it) but I have not completed my site yet. I dont want to publish it until I feel ready to start a business and I feel like I need to do at least one more wedding a senior or 2 and a family or two.
