Small businesses need professional marketing but can't afford full-time specialists or agency retainers.
Build a service where owners define projects (website refresh, social campaign) and get matched with pre-vetted specialists working as a temporary team.
Charge a percentage of freelancer fees or monthly subscriptions for ongoing needs.
Start with a few core marketing specialties before expanding the talent pool.
Risk: Quality control is challenging at scale, and clients may expect agency-style management.
