MLS Integration / Plugins for Crexi, Buildout and Brevitas

Site URL: http://sitedoesn'texistyet.com

I have a client that is looking to build a website that will integrate with a few MLS type services: Crexi.com and Buildout.com. Has anyone made these connections before to Squarespace? If so, I am wondering if you can share a bit of your process. We are also open to hiring someone to help with these integrations.

My client also uses Brevitas for marketing and would love to know about any possibilities to link here as well.

Are there any experts out there that deal in the Real Estate sector that can help with these integrations. Thanks!
