Beginner friendly: Moderate

Starting a Newsletter Sponsorship Brokering and Ad Sales Agency can be moderately easy for beginners. With no special skills or background, individuals can begin by reaching out to newsletter creators and businesses interested in advertising. Online resources like guides and tutorials can provide insights on negotiation strategies and industry trends. The key challenge may lie in building a client base and establishing credibility in the industry, which can take time and effort. However, with persistence and a strategic approach, beginners can start earning a profit within 2-4 months. I'd rate it a 2 because while it requires learning and effort, it is achievable with dedication and the right resources.
