1. Create a subscription-based website (something weird like magaraja.com) that sells Q and MAGA stuff of all sorts, and also "health" supplements like testosterone boosts, penis enlargement pills, whatever else these people consume regularly.
2. Don't just sell memberships to these people to buy your overpriced garbage, but tell them you are selling them a business franchise.
3. Get all of the MAGA people you sign up to have parties and invite all of their MAGA friends to be business owners under them.
4. Cash in your billions.
