- You have a public form - request to order promotion on YouTube, and any Community member, Guild, Influencer can fill out the form (first come first service); Again, it should be open form with 24/7 access for everyone - name, requested project,
- Community members able to chose any YouTubers from your list or suggest own;
- After that , Star’s guilds agents starting work with the requests, exclude all projects which have own Marketing budget or promoted by any private marketing companies, work with YouTubers to get the best rates, then
- prepare a list of YouTubers for promotion for Near Community and Marketing DAO councils, advisors here on the forum, then
- Community and Marketing DAO review your proposal, bloggers (at the point you should be ready replace YouTubers or remove some of them).
Overall I believe, you need to work closely with community members.
Instead of shilling Flying Rhino clients, use Stars guild twitter to promote videos which were produced and paid from Community Treasury.
In the other hand, if you disagree with me, Flying Rhino can pay to your guild for the promotion. Here is a link on the opportunity.
Ps: Man, it’s just my opinion. If I got you right (and you mentioned about it before) you can call to @Grace and get approval for your grant without any annoyed questions from me 
Furthermore, you can try yourself as a Marketing DAO council, propose yourself, when pull of candidates will be opened.
Thanks
