When someone is not willing to sign an agreement with you find out the real problem. Is it the price, or the type of service you are offering, or some other challenge the customer is facing which has nothing to do with your agreement?
Once you identify the real problem this also becomes a source for creating a solution or breakthrough.
If the issue is price then lowering the price is not the only solution. You can either reduce price with a customer or increase value to justify the price. When a client is given the option they usually do not want to reduce the value or service. They like reducing the fee but are not happy to reduce the service.
