It's an interesting idea, you can try selling direct to agents - but they're pretty stingy lot.
Good chance you know a real estate agent if you live in US or Canada. Just ask your extended family and friends if they know any agents, you'll get a call within a week lol - then flip the script, as they start trying to sell you on how excited they are to help you buy a home - tell them you have a bunch of leads and if they'd be interested.
Give them a small sample and say that if any of those turn into a lead, you're happy to sell the next set for a fee.
If they're not interested, ask them to refer you to other agents they know - in exchange for a small reward - a gift card or tell them you'll pay for a home inspection (~$150) or buy their house warming gift for one of their clients ($20 for some big houseplants) if they do it.
