Made an enquiry through local agent finder and they recommended a real estate agent. When we met the agent we weren’t overly impressed, does it mean we still have to use them?

Hi David,
Provided you haven't signed an exclusive authority with the agent, you are not compelled in any way.
Have you been to auctions and open for inspections in your area? You want these to be well managed and have a good number of active enquiries. See who follows up with you after you register and see how they interact.
If you would like to discuss, feel free to give me a call anytime 0435. 474. 498
Regards
Scott
