Custom-build a very simple WordPress plugin

I need a WordPress plugin expert to build an incredibly small and simple plugin for me. It's a customer data plugin that interacts with a data entry page and a data-display page in table format. Yes, I know that there are tons of WordPress plugins out there in the world that already do this kind of thing. I don't want them. I have my reasons for wanting this done as a custom-built plugin. The plugin will be the foundation upon which I plan to add a number of features in future versions of the plugin. For now, I just want a simple, custom-written plugin (no stealing someone else's already-written code!) that accepts data entry and modification on one page: [login to view URL] and then stores that information in a custom table in the DB. On a second page, I want the plugin to generate a table that displays all of the information stored in a customer WordPress table. Separate shortcodes for each page are perfectly acceptable. The name field's records will include links to the data entry page, with the record's data loaded into the data-entry page. I expect you to use built-in WordPress functions whenever and wherever possible. The DB table should use the database table prefix defined in the [login to view URL] file. Your code should be as short as possible and clearly documented internally. That's it. That's the entire job. If you win the job, I will give you access to the above-listed website's WordPress back-end, where you can test the plugin as you build it. Handle this job well, and you will get first priority for doing the next version of the plugin. Please indicate that you have read and understood all of these instructions by beginning your bid with this exact phrase: "Your instructions were very clear to me."
