I am looking to services like smugmug, zenfolio, fotomoto to automate this process. But all of these are not cheap (to me anyway, I'm just an amateur photo-enthusiast).
These services really aren't that expensive for what they offer. A website, unlimited backup of your image files, file delivery/download, and print sales. All for approximately $150/year (plus a % of the sale). You can recover that from the sale of one or two 16x20 prints. If you aren't selling two prints per year to earn $150, then you don't need the site.
Now it just becomes a question of what your time is worth.
People still buy prints. Whether or not they buy them from you depends on if you can get them to your site in the first place. If you don't have steps in place to get people there, then you probably won't have any sales. I have found that some sales are spur of the moment, so "buy now" will get you a few sales that you may have missed out on with an "email me" method.
