This would be an excellent candidate to add as a project for community based fundraising on OpenCollective.
@JanJo If you are willing to help administer the project, I suggest writing up the initial scope and clearly defining the desired features and interaction with Moodle. Once that is in place, post it to the OpenCollective category here requesting that this be added as a fundraising goal.
Part of the challenge will be estimating the initial cost of the work and setting a fundraising goal. Software development can be significantly more expensive than many community members expect, see Expectations of costs for a discussion around this. This project would be best approached from the perspective of fundraising to support a developer that has their own interest in working on the Moodle integration, rather than thinking in terms of outright hiring someone for the implementation.
