Personally i agree with @cm-steem that this is very broad. If these ideas were to be implemented it would have to be spread across multiple people.

We need categories of jobs and peoppe who attend to those said jobs. There is a reason we have development marketing etc seperated. Ive seen what you have done and how you communicate but dont know you well enough to agree to such a position at this time however not against your taking on a category of roles to alliviate the work load from the list.

I like your ideas but the workload and responsibility is high and the concerns myself. The above tasks is not simply a one person job.
