Custom database management plugin??

I know this is late and I’m sure you’ve already found a solution, but for something simple you can always use the contact form 7 (https://contactform7.com/) in conjunction with the contact form 7 database extension plugin (https://www.ads-software.com/extend/plugins/contact-form-7-to-database-extension/) they worked great for me in a completely different application, but basically it is completely customizable so you can pretty much do whatever you want. Since this may be long after you found a solution, I left it for others who might search for a similar answer.

Thanks for the response. I really do appreciate it. ??
