Could it be that with a July time frame they are not interested? I have looked online at homes, and in one case found a realtor based on the home I found, the house was in contract, but it was a great realtor, I ended up buying a different house with her. When we outgrew that house, I used her again to get the next house which wasn't her listing, but was on MLS. What I liked (personal preference) was she just opened the door and got me access, I knew what works and didn't work. She just let us go through and check out stuff and would add a comment if I missed something.
We bought something out of state recently, and that realtor was good although she was recommended by a friend. Same MO, she gave us a list of 20 homes to look at and had us pare it down to about 4-5 for the day. We met her and just went through and she allowed us in, let us roam through the places, and pointed out anything we may have overlooked. We may end up buying again in the same out of state location and I will definitely use her again.
My advice, use the web to zero in a bit, once you talk to a few when they call back, see if you connect with any.
Good luck, happy hunting
