Hello, I am new to freelancer but I have 2 years of experience with PHP and can make this feature easily. I can get this to you in probably 1 day (I put 4 just in case because you didn't specify the complexity). The related courses I have taken that would benefit my performance on this project is one in optimized form design for the end user. Related experience I have is that I have previously built an admin control panel for myself which displayed a lot of statistics in an organized way (visual graphs, tables, etc.).
I hope to get a chance to work with you on this project, thanks.
