"Your job as a sales person is to find the 20 people in this town who have a $100k problem."
You may meet a lot of people who have a $100 or a $1,000 or a $10,000 problem along the way. Be honest that it's not the right time to work together and move on (for now).
It's tempting to want to work with these customers but in the early days, you want to find people with a really big problem. As you grow you'll be able to expand your reach.
This is hard advice to follow because leads are so hard to come by at first and because you want to help everyone if you're passionate about what you're building.
Keeping prices high helps with this because it will disqualify a lot of people that would probably waste your time anyway.
