This is a great contest and I think you are doing great work and I'd like to support your efforts with what I can do. Something I can do is make simple promotional animated videos and I'd be happy to make some for you.
Currently I'm making animated videos to promote steem contests outside of steem for free (I announced the offer here) and I'd be happy if you decided you want one to promote your contests and spread the word about steem in the meantime.
Here's the first one I made about a sports contest, but I'll be happy to revamp it to fit what you are doing.
We can also work on a promo video like this one for the accelerator hub in general.
Hello Dave, thank you and we are interested in getting stuffs like these for the purposes of promotion. Are you on Steemit Chat or Discord? @ejemai will contact you.
I'm on steemit.chat, should get on Discord, but haven't done so yet.
