What is the best and easiest method to get a list of previous clients? This has been bothering Mary for awhile now. She needs to be able to gather a list of clients that visit her website and purchase items. Mary has decided that her site is outdated and she needs to hire someone to build a small business website from the ground up so that it will automatically gather clients email address for future promotions. Mary has began searching on line for well know web developers that have a great reputation. She would like to see some of their previous work also.
