Development Acquisition Tactics - Texas

I just signed on with a highly capitalized family office with the means to close quickly on anything within the $1M - $5M deal size range in Dallas. Didn't come from a M&M or brokerage firm with any training on prospecting or cold calling techniques. Have moved into a more acquisition heavy role in terms of finding value add retail development assets (covered land play, blend & extend, redevelopment deals mainly).

Hitting the phones and finding deals is new territory for me, any techniques or resources that could assist in the transition?
