Why would someone need a developer for photography website when there are plentiful photography hosting platforms? Smugmug, Photoshelter, Zenfolio – these three are being the most popular. You can easily set up and customize your photography website up to your taste and requirements without the hassle of working with developer.
This is the site under my maintenance which is hosted by Smugmug – Posters.org.
You can set up photography site on photography hosting platform in an hour and start selling photo immediately to test the market. Working with developer can take months, and will not be even close time-wise, budget-wise and feature-wise to professional photography hosting platform, and it does not necessarily result in a good site in the end. In a couple years you will need to either redesign your website or develop it again from scratch because web is changing.
