Looking for your experience, advice, agencies that deal with investors in pursuit of their RE License!

My story....

Have a small RE investment company that buys, rehabs, flips (now getting into the rental game) and have worked with a few agents over the years (Your Castle Realty, InMotion Group Properties). With the business goals (plus wanting to cut costs on sale of properties) made sense to get my RE license. I'm in the process of that currently. My hubs and I run the company and sell/flip on average 2 houses a year (he does a lot of the work himself/manages the projects) - looking for agents with experience on the investing side, turned RE. A few specific questions: 

1. 1. Any advice in finding an agency that may be geared towards investors who want to sell their own houses, not necessarily become a full blown agent? 
2. 2. Any specific advice for those out there who have done this/not done this route? 
3. 3. Any agents out there in the Denver metro area who may need an assistant? Hate to throw a blanket request out there - I'll be personally reaching out to agencies as well. 

Am all over the information on the forums here, want to attend some upcoming events around Denver in the New Year, and am all ears for learning. Really appreciate this community and all it's members! Thanks in advance - cheers!!!
