Website Creation via Wix - Looking for Wix Specialist

Hi we are about to set up a website in German for a project to protect colombian rainforest. The website is going to include videos and more content about the project and the area. Goal of the website is that visitors subscribe for a membership to protect the area. There has to be a process to collect contact data and create a database. Payment is either going to be via Bank account transfer or credit card, depending on the comissions. The website is currently accessible under https://www.reservanatural.ch/ (only a template yet). We are looking for a freelancer to bring us up to speed, give us ideas or references how you have done similar projects in the past.

As an inspiration, we like the following page of a similar project: https://www.o2reserve.com/

Best regards

Stephan
