Challenges building team as a Real Estate Rookie

[Gee Williams]

Hello All - I am a real estate rookie. I am on the tail end of finishing up my first flip that started in March. I have experienced some issues with our contractor, which I am becoming aware that contractor issues are more common than not. I recently read Bigger Pockets "How to Invest In Real Estate" and I listen to David Greene's podcast at least 2x a week. So I have been working on the task of building "My Team" as I plan to purchase 2 more properties to flip by the end of the year. I came across this investor that bragged about how good "their" contractor was. So I asked for their contact information. The investor stated that the contractor is "WAY TOO BUSY" on their projects so could not share their information. I was taken back from their response, because 1) I just asked for the contact information. I don't even have a job for the contractor to work on at this very moment  and 2) I  felt it was a very selfish response. Like my single email to contact the contractor would take away form the investor's project...so is this a typical reaction I should expect from seasoned investors, they like to hoard all of "their" team members? Or is there a more politically correct way for me to request contact information so I can network and build my team as I scale? Any guidance is appreciated!
