@websensei - Sorry for uber late answer!
Here we go:
Do you know any blockchain based project providing web hosting services?
No. There is none.
Do you think that the blockchain technology will work out in web hosting services?
No. Simply because p2p technology by default is uber slow. Hosting is al about speed and latency. Even all front-ends now in a blockchain are being hosted in 80% of cases by NGINX (some rare cases Apache) with redis as cache gateway. Why ? Its super fast and its stable.
What online tools do you think are particularly useful in marketing and sales? Can you give some examples?
Steem Marketing or Globally www ?
Do you know any talented blockchain developer who could become the member of our team?
No, but i do have company/team who would be joining forces with your time if you are interested.
Which one is best in your opinion:
cooperation with existing decentralized data processing platforms?
creating everything from the very beginning?
We are currently testing
a) bitshares blockchain
b) steemit blockchain
c) multichain (bare naked blockchain)
Will let you know more once i get answer to my previous question.
Cheers,
Lucifer
