Just heard back from the business owner. Everything is OK! He said he totally understands that I deserve to be paid for my work and he has no problems doing so. As a matter of fact, he sent me a list of additional items to update and add. Friendship remains intact, unless he now sees the relationship differently, only time will tell. Thanks for all the insight from everyone.

By the way Matt; I don't know about other companies but where I work a Desktop Support Analyst is responsible for creating and maintaining a standard PC image for deployment on new PC's and laptops and updating it as needed to keep it current, maintain all PC hardware, install both client/server and standalone software and maintain all software installed, including the OS. We also troubleshoot network connectivity issues maintain network and local printers and write macros and scripts to automate common tasks for the end users. There's a lot more but this should give you an idea.
