I can create a spreadsheet for you with client details. If you would like, I can set this up in Access with a form for you to use to input new records as they come in. The form will protect the data already in the database and will be much easier to fill out than scrolling to the bottom.
If you do want it to stay in Excel, I can certainly do that for you as well. If you want anything automated, please let me know and I can see what I can do for you. My goal is to make something user-friendly but not complicated or huge in file size.
If you select me, I will start working on this right away and will get it to you ASAP.
