Hi
Good luck.
A few options:
1. use AB testing: show different prices for the same service (either using different pages), or if not possible, show one price for 1 or 2 weeks, and another price for the other 2 weeks, and so on (3-4 times) until you find the ideal conversion price.
2. Use a survey for existing clients - ask them how (much) they value your business - you might be surprised for the better. Don't forget to offer an incentive for people who take the survey.
3. Raise prices, but add something to the new offer - even if seemingly small to you. this way, they are paying a bit more because they're getting more (which makes it feel justified to them) and not just because you raised prices.
Good luck
