We have a local online cycling forum with a section for newbies to introduce themselves. People often include that they are looking for people to ride with in a certain area along with the type of riding they do, their distance and pace. I have responded to a few of them myself to invite riders in my area to ride with my group. You might check into that.

I haven't tried it yet, but there is also a meetup group in my area that does rides. You might try that.
