mailing application - phplist?

I manage websites for over 100 small businesses. Many of my customers want to have email signup forms on their websites and then send out monthly newsletters. However, instead of signing up for a service such as [login to view URL], they want me to handle this for them. I generally prefer applications built on open source software because it is easier to find someone to make changes for me. With that in mind, I had someone begin this project using phplist (they abandoned the project). I like the features but it seems a little difficult to use. However, if this is the best solution, I can live with it. Please see the attached for the details of what I am looking for. In summary, I am looking for: 1. A mailing application that is installed and ready to go for my first customer. 2. Instructions on how to modify it for additional customers. NOTE: Please feel free to ask me specific questions that will help you to formulate a bid. However, DO NOT SEND ME ANY GENERIC MESSAGES TELLING ME HOW WONDERFUL YOU ARE AND THAT YOU ARE INTERESTED IN THE PROJECT. MESSAGES THAT DO NOT CONTAIN BID PRICES OR SPECIFIC QUESTIONS WILL BE DELETED. IF YOUR PRICE IS COMPETITIVE, I WILL LOOK AT YOUR PROFILE. Thank you for taking the time to read this.
