LibreBase freelancer to guide DB owner on enhancing his application.

I’m looking for an experienced LibreBase developer, who communicates well in English, who will work with me on an on-going hourly basis to enhance my DB application. I am looking for guidance and advice in adding buttons, building queries, developing small macros, etc., as well as resolving issues implementing the code/changes. I want to make the changes to my DB application myself so that I learn as we go. My application has been operating (with limitations) for about a year. I currently have about a dozen functions I’d like to add to my DB application that I don’t know how to. I’m sure there will be other enhancements where I will need help as well. I want to work on one “function” at a time on a part-time basis, translating to up to several hours per week or so. This would be an on-going engagement. My DB application consists of a single LibreBase form with numerous fields, some buttons and checkboxes tied to three cascading tables. The top table is linked to a second table, that is tied to a third table. The second and third tables have a one-to-many record relationship to the previous/higher table. I’m currently running LibreOffice version 24.8.3.2 (AARCH64) on a Mac under MacOS 15.6.1. Java is Oracle 23.0.1. I’m using LibreBase’s built in DB engine (HSQLDB). All macros are written in Basic.
