The price depends on te effort the designer/developer needs to put in
To put this in perspective. Any decent designer can install and drop a template on a store and have it up and running, ready to add products and take money in a hour
That is the bricks and mortar equivelent of renting a shop, and buying some clothes racks and a till
What you are really being charged for is what happens next - the developer/designer then turns the bare shell of a store into a commercially acceptable product. Depending on your needs, it could be a few days work, to several months worth of hard work
This is the bricks and mortar equivelent of getting the shop fitters in
Any "GOOD" designer/developer will also secure the store, and train you to make backups an the like
This is the bricks and mortar equivelent of getting the locksmiths and alarm guys in, and employing a security gaurd
Any "GOOD" designer/developer will also sort the SEO and internet marketing framework out, and work with you to outline the long term marketing plan
This is the bricks and mortar equivelent of getting all the sinage, window dressing sorted
Any "GOOD" designer/developer will also install and sort out and bring you up to speed on analytics, webstats etc. This is your toolbox that helps you understand traffic and conversion
As I mentioned at the begining, you can rent a shop, and buying some clothes racks and a till open the doors, and make a few sales. Or you can rent a shop, get the shop fitters, locksmiths, alarm guys, signmakers and window dressers in and make lots of sales in a secure and beautiful environment
