Lisa, you may not need a partner, you most like need the right "consultant-representative" with the right the marketing/sales skills.
You are way ahead of the game because you have admitted that you are not a sales person, thatstrue. I can tell because you have predetermined that you want to go get advertising as your monetizing scheme.
Frankly-WHY did you select that? Please dont do that. You are not ready for nor positioned for that being a logical revenue source.- You have no customers nor any large following yet that advertisers would need to see before they even considered investing ad money with you.
Instead, I'd suggest finding a great consultant who knows how to deeply understand what you have now, what you want to accomplish and can then find the appropriate target audiences for doing all of this, those who will pay for what you have, pay an annual subscription directly, not advertising.
Doing that first gets you the gigantic following, membership, audience upfront, earns cash upfront but then can be "sold" as a place for folks who want to reach your audience must go.
You cant sell from an empty store so to speak and your store is empty re its natural market following-connection-loyal "customers'.
Thats also researching beforehand to uncover the correct audiences, who they are, how to reach them where they hang out and get them to say "hey-thats me-I need to connect with, buy and use Lisa's stuff.
