Hi there, I'm Matt Sergei (do call me Matt, please) and would really like to help you -
with all the knowledge and experience in Internet marketing gathered in 26+ years. So:
1. How do you intend to sell your card set? From your website only, on Amazon, both, other option?
2. Do you have digital image versions of all cards (and possibly a box)? Asking because of intented video creation, one main and several other supporting it.
3. Do you plan to do "content marketing" e.g. writing blog posts, adding interesting facts in social media posts, do some giveaways etc? Or just want to have one or few sales pages and well positioned videos and other multimedia doing the work (e.g. being a lead magnet leading to a sale of your product)?
I can do a lot, with dedication and "tricks on the sleeve" learnt by following "underground" Internet marketers, several of them millionaires now.
Either way, first I need more information to see the possibilities and target market.
Regards and hope you're safe,
Matt
