Here's the skinny:
Back in Dec. I started a project for my brother's boss' wife (figures, huh). Seemed easy enough - she wanted a design insert for these items she was to pitch and get on store shelves. I quoted her twice - once for all the items she talked about (2 logos, 5 designs) and again for just the logos and one design. She agreed to latter being on a tight budget. Understanding that I scaled down the contract - only one round of revisions, no alt designs. Clean and simple - keep in her budget while making it worth my time.
Fast forward and it's been stupid nuts. She's changed one logo at least 3 times, had more than that for the package. Only thing she's kept in check is the last logo - one revision and we were done. I've explained to her in e-mails and over the phone that she's gone past this, and I wanted to start charging the hour rate that kicks in when this happens. Her reasoning why I shouldn't? We were almost done, and she didn't feel she had her 'one revision' yet and was let down that I didn't "put my own spin on it" effectively doing the work twice.
So I felt a little sorry for her (and she's connected to my brother's job in a roundabout way) and believed her when she said all she needed were some final tweaks to make it perfect.
Get an email over the weekend saying that her 'marketing' friend took a look at it and said there was all this shit wrong with it and should be changed. So now she wants even more work done based on someone else's input. How do I tell her to fuck off (or that I'm charging extra) while being as polite and professional as possible? And how do I do it while being sure my brother doesn't catch blowback if she decides to get crazy on me?
