Looking to invest in St. Louis, MO

Hello, i'm looking into investing in the St. Louis area. I am beginning the process of searching for my core four (realtor, mortgage broker, contractors, and property manager). If anyone has any recommendations or contacts they would be willing to share I would really appreciate it. My goal is to find distressed properties and BRRRR them, and my end goal is to make my core four a lot of money. Feel free to shoot me a message or comment below!
