WIX is honestly the worst website template/host for photography. Don't waist your time, your stuff looks good, but WIX's interface is brutal. Max 5mpg file size? WFT?
Here's a bunch of other sites you should check out that are all 500000000x times better.
(What I use, link in sig, $50 a year but you don't get much customization)
Heck, even Tumblr is better than WIX and you can use your own domain for free.
The other option is to pay Joris (or bribe him) to make a site for you....
As for content be really selective when deciding what images you are going to show the viewer. I'd say that less good work is better than lots of filler, if the image is at all sub-par, it doesn't need to be there. Also, make sure you get a photo of yourself on your 'about me' page, it's a must. Anyways I hope that helped, PM me if you have any more questions.
