Hello world! I am new to this community and excited to start this journey.

I was wondering if you had thoughts/recommendations around:
1. When is a QofE needed? Are there instances when you don’t require it?
2. Do you have recommendations for providers that do QofE?
3. What should I look for when vetting a QofE provider?
4. What are the price ranges I should expect?

Thanks everyone in advance!
