PokeCommunity is a community, not an advertising board. If you want to participate in the community, that's great! You can advertise your collection via your signature (you can put links in it immediately) and post around and people will see it. In addition, there's a section on the Pokemon TCG you can post your video in once you get 15 posts I believe, since you're not allowed to direct people off-site and will have to embed it. But before you do that I would recommend you PM the moderator of that section, donavannj, as I'm not 100% certain if that's within the rules there since I don't play the TCG.
I know this is a lot of information so feel free to PM me if you're confused!
