If you're not a good salesman, and you don't care about conversions, then give them your price. If you have a sense of sales, just hold on...
Before you continue, You do need a sense of their budget before you go into details
(if they give you a price in mind, work with them if it suits you, if not... DUMP THEM FAST)
(if they don't have a price in mind, attempt to ask questions to qualify them for the service)
The key to commanding the prices you want are to build value and to understand the target customer you're going after.
OBVIOUSLY you wouldn't be able to command a higher price at a local coffee shop as opposed to charging a lawyer or an accountant... So choose your target market, and build value as to why they NEED your product and why you're the right decision for them, and not a competitor.
