Can I do this with the plugin?

Hello, I am looking for a plugin to be used on photographer's web site with the below requirements. Since you do not have neither detailed demo nor trial version, can you kindly confirm that with the purchasing of plugin + addons bundle, I will be able to realize this:
1. Synchronization with clouds (Dropbox or OneDrive) or at least synchronization with the file/folders structure at the web server.
2. All synchronized files are kept locally at my web server (not links to the cloud images).
3. Tree of galleries at the frontend as following:
- First level shows list of galleries.
- Second and further levels show either a list of galleries (sub-galleries) or a gallery.
- A list of galleries must be of square of portrait images (either or).
- A list of galleries must have titles (name of the gallery or sub-gallery)
- A gallery can be of masonry style.
- Photos in the gallery shall not have names/titles.
- Do I need to create every gallery/list of galleries manually or it can be created automatically from files and folders structure in the cloud (or in the server files)?

If the product does not meet my requirements I can get refund for both plugin and addon? (Refund policy mentioned that you will refund only one of them that I am not satisfied with, but I cannot use addons without plugin and vice versa).

Sorry for complicated question. I really like your plugin functionality but lack of trial/demo version makes it difficult to understand its real capabilities and how flexible are the settings.
