I can have a basic 5 to 10 page web site up and ready within a week. Bigger sites take longer to complete. E Commerce is more involved, and depends on how much information you have available on your products. For example, do you have photos taken already? Do you know the weight? Do you have a description already in digital form? Do I have to create a description, or type each one out?
If you have your homework done, meaning you have all the text and images for your web site ready for me, the process is much quicker on my end.
