As you can see, Angle, any agent can search the MLS for active listings meeting your criteria.
However as you are likely to realize once you are in the middle of the purchase process... the really valuable thing that a buyer broker brings to the buyer is experience, their ability to negotiate and their skills to educate the buyer about homes, areas, condition, inspections and repairs. You will want to shop for a buyer broker who is open and communicative, who will listen to your concerns - but also educate you on the process. You will want someone who keeps you in the loop, who communicates well and navigates the process for a fair and equitable outcome - keeping your liability low and your satisfaction high.
It looks like one or two of the agents who responded to your question earlier made an honest effort search for you. If I were you I would call them and have a discussion. Let them know what you want and what is important to you, and see if their area of expertise and/or communication style seems to fit your lifestyle. Almost everyone starts off shopping for a HOUSE, when really they should shop for an AGENT. I hope this comment adds perspective to your quest. Best of Luck!
