However, we have been in this business long enough to know that unsolicited manuscript submissions from an unpublished author just beginning to build a platform is a long-shot with most publishing houses.
First, platform doesn't matter (unless you're talking about non-fiction).
Second, submitting to agents/publishers is not a long-shot if you are writing good work and it's professionally presented.
As others have said, I think your goals are laudable, but I agree that the publishing aspect doesn't seem that thought-out. What is the point of publishing these works if no one is ever going to buy them? I'd suggest focusing on maybe teaching the ins and outs of submitting to literary/genre journals, since that would get the work out into the world and in front of an audience (assuming it's good enough, and you target suitable journals).
