Is Hiring a Posing Coach Worth It for First Time Competitors

I am twelve weeks out from a show in Vancouver and I am considering hiring a professional posing coach. I have been practicing in my basement with a mirror but I am worried that I am developing bad habits that I cannot see myself. The cost is about one hundred dollars per hour which is quite steep on top of my gym membership and food.

I have seen some online coaches who do video calls but I am not sure if that is as effective as an in person session. I want to make sure my transitions are perfect because I have heard that is where most people lose points.

Is it worth the investment for a novice? I am already spending a lot on my diet and supplements. If you have used a posing coach in the past did you feel it made a significant difference in your final placing? I really do not want to go up there and look like an amateur.
