You should post this in the "English" section, not the "Spanish" section, so that English speakers can see your post. You are currently broadcasting your post to other Spanish speakers ;)
Another note - it is very hard to find language exchange partners. It is much easier to just pay for lessons with community tutors or professional teachers. If you really want to do language exchanges, you should just go through the "language partners" section and message English speakers, one by one, maybe 50-100 times before you find someone who is both enjoyable to talk to and willing to practice consistently with you.
