I've worked on many projects where I had to overcome someone's decision to go the cheap way, yet when starting my own projects I'm tempted to go the cheap way.
The profit margins using cheap inputs can be enormous.
Yet those cheap inputs and methods create standards and expectations, which future clients and colleagues will measure you by.
This isn't about being expensive- its about being on the good side of the value equation between you and your client. Even if their budget is $50, you deliver (in their eyes) $51 of content. Going the cheap route too often delivers only $45 worth of goods- and eventually the client will figure it out.
In the long run, being known as "the guy/company/organization who does things on the cheap" will cut into future profits.
