I have built a small business to solve a similar problem for Property Managers: to manage all their phone-based intercoms (Doorking, LiftMaster, etc.) in one easy-to-use (and patented) SAAS UI. I did work with a similar integrators like RemoteLock.com (but love your approach a lot more).
Would love to work with you, check it out at www.DropBy.io and feel free to reach out to me at [email protected]
We removed pricing, one reseller wanted that out. But good point, I think we should add it again and be transparent since his business is good but not good enough to do so.
