Need Expert to Find Established Websites Available for Purchase (Domain + Social Presence)

I'm looking for a consultant who can help me identify and acquire an existing website domain that has an established online presence. I specifically need a domain that has been active for a few years, has some Google search results, and ideally has social media accounts (even if low activity). The goal is to purchase the domain (and associated online presence) within a budget of $10,000 to $15,000. I need someone who can: 1. Research and shortlist potential domains that meet these criteria. 2. Verify their search presence and social media accounts. 3. Ensure that the domain is for sale or that the owner can be approached for acquisition. I’m not buying a full business—just the domain and online presence. If you have experience in domain research or acquisition, I’d love to hear from you!
