General Crazy Website Question?

Try looking at your problem in this light: your potential client (let's call them PC) has a pre-existing agreement with another designer, who's already provided some work for them—the fact that they're not happy with it is not the issue we're dealing with. What we are dealing with, however, is that the PC is willing to go behind the back of its existing designer and commission someone else to do what he has already done. The fact that they haven't resolved issues with him shows a lack of ability to communicate on their part (yes, they're in a unique circumstance with his condition, but it doesn't change the issue).

I would caution you from pursuing professional relationships with people who themselves aren't acting professional. I've learned the hard way to avoid jobs like these.

I agree with Zak. Based on my experiences, 100% of the time I've worked with a client that was openly unhappy with their previous designer wasn't the fault of the previous designer at all. It always tends to be incorrect expectations on behalf of the client, and you will now inherit those same unrealistic expectations while taking on their project.

Many times the most difficult decision you will have to make is saying no to a project/client but this will save you from getting massive headaches along the way. There are some red flags in what you are describing. My advice to you is to stay away from clients like that.

Thank you all for replying, much appreciated! Agree with you all to be honest. I hear a lot of designers describe the same point of view.

No problem James! Good luck and all the best in future projects.
