Looking for someone to write an app for the Arma 3 commuity

I am looking for someone to write a program either local or web based that will Edit or Create .hpp scripts. It needs to have a local database that you can add classnames to or remove classnames from. The idea is that you need to be able to open an existing crafting.hpp file and load the existing Recipes, edit existing Recipes and/or add new ones. It should be a graphical method instead of having to edit code. I want to make it simplified for server owners and such to add crafting recipes or remove them or edit them.

Here is the existing HPP file for reference on how the finished product (script) should look and for Syntax examples.

I tried my hand at using C# but it has been at least 4 years since I did any software development.
The program should be GPL’d and on Github and able to be run on Windows, Mac or Linux.

I am open to monetary compensation if reasonable.
