Dummy dropshipping websites

Good morning everyone,
I hope this post finds you very well.

Let's assume that I have set up some dummy dropshipping websites and connected them to some CC gateways, using darks. Each website process 20k$ monthly.
As many of you may imagine, the purpose is to process funds related to other delicate activities.
The websites are quite temporary. I do not expect them to survive more then a few months. But for me it is good. It is easy to create others.

Now, I would like to enquiry you, community, about two issues.

First.
Wich documents I may expect to be requested from the CC gateways?
I can easily, provide them any type of invoice, agreement or shipping doc.
Only storage/warehouse photos I cannot, for obvious reasons. In this case is there some of you that can offer such storage's photo service? If yes, I can create new websites related to the photos that you can provide me. Example: photos of clocks storage or clothes storage --> New websites related to cloks or clothes. PM for more.

Second isssue.
As explained, to date, I am working with dropshipping dummy websites.
Established that I would not have any products for real, to sell, in any case. Would you recommend to switch to other websites typology? Like software or digital products websites.
If some of you can provide this typology of disposable website please PM.

Thanks for any help!
