Some times I get to reject some design projects for some good reasons, but one re-occuring issue is Clients changing their mind on the agreed layout, or project goal right at the middle of the project. then you have a 2weeks project in your hands for 6weeks. Question is what do you do when a client is taking more (value) time than he bargained for, and how do you manage such clients and help them achieve a clear cut objective (because some of them dont know what they want).

You tell them that sure, you can do it but that it will cost extra. If they agree, you revise your statement of work. If they don't, you walk. Simple.

thx, something useful i found

Always get a percentage of your pay upfront. At least if you plan to walk you are not walking in the negative. Time is money.

I got burnt once.
