List your Google Plus Profile and Page(s)
Last time, we did this with Facebook Fan Pages, so I thought we should give it a try with Google Plus pages as well.
Hopefully, by doing so, you can find other profile and page owners who are willing to reciprocate and add you to their circle(s)
You could try adding the people who list their profile here and hopefully, they will do the same for you. I suggest that you ‘subscribe’ to comments so that you can see all the new profiles and pages as they are listed. This could provide you with a steady supply of leads for mutual cooperation, etc.
No one is obligated to add to circles, it is completely up to the person involved.
Let me know if you find this page useful.
