クラウドファンディング運営の為に最適なものを探しています

I am looking for the best one for crowdfunding management.

I posted it once, but the explanation is too insufficient so I will post again.

I am a beginner. I would like to operate “cloud fund”.
However, it is risky to start suddenly, so I’d like to start by testing with WordPress.
So we found various themes and plugins. Among them, I found “Envato” and “IgnitionDeck Enterprise”.

Regarding “Envato”, you guys know that. For “IgnitionDeck Enterprise” please refer to the following URL.
Https://ignitiondeck.com/id/ignitiondeck-enterprise-white-label-crowdfunding/

The prices of these two are different.
“Envato” is $ 59. “IgnitionDeck Enterprise” is $ 499. A different version of “ECHELON” is $ 149.
I can not understand these functional differences only by looking at the overview.
Outside people will use my page.
I will use not only myself, but also customers.
I would like to know whether it is functionally functional from that point of view.
However, since it is a beginner, I do not understand easily.
Those who knows, I hope you can teach me.
Thank you.
