Hi, I would like to work with you. I think I have some theoretical cryptography skills to add. I would like to ask how/if your storage will be mathematically proved? It seems very exploitable, which wouldn't be good if the concept came to be worth lots of money. I think you need a format of proof of storage, but I'm not sure you have it yet. Thats ok I already did that work so I can help you out there.
Also, the current "datacoin" is not like your proposal because it is very limited. Don't be discouraged by that at all. It is simply a way to prove a file existed at some time, not a way to have distributed hosting of a file.
