Community help for Payzen payment Isotope extension ?

Hi everyone,

One year ago, I started a website with Contao + Isotope. For online payment, my client's bank uses Payzen which seems to be very used in France an in Europe. So I contacted Lyra / Payzen.
The extension didn"t exist and Isotope developpers asked Lyra to pay for it. So Lyra started developping it itself. But my project was stopped and the extension is actually in beta (I got it).

For finishing it, Lyra is asking me how many transactions/year could be concerned. This is for a little association so not so many.

Then I would like to know how many of you could be interested in using Payzen payment method for Isotope ? Or if Terminal 42 or the community could be interested in achieving the work. (I got the beta files)

Thanks
