Some thoughts:

• The project does not need (more) funding - but if anyone has some urgent needs or feature-requests, a monetary compensation would allow me to spend more time on this project and prioritize the urgent feature request.
• I will only accept payment after the work is done. (Bigger tasks needs to be split into milestones with funding after each completed milestone).
