1. We don't have trial version of the extensions for you to try. However, we do provide money back warranty, so if you want, you can purchase a copy of the extensions to try, if it doesn't work as expected, you can request us for refund
2. The features you asked about Joom Donation, unfortunately,not supported. So if you want to have those features, you will need to hire a developer to customize it for you (but it is not hard to implement those features)
