How do architects and designers sell their services if they very often speak different languages with the client?

Architect and designer about beauty, about convenience and quality materials, the customer about square meters, about cheaper and faster to build and more expensive to sell, this is if a developer, and if a private client, “I want the best, but I want everything to cost little and to be able to live yesterday”? How to be convincing for such customers, but at the same time not to lose the quality of design and future construction? How to extract new sales from the design and construction processes? Our speakers will talk about these topics, and we will involve the audience in discussing them.
