I have a great idea for a business which I can develop myself but in order for it to be a success I need to partner with a designer as my design skills are non-existent. I would need someone who is capable of website design and someone who can do design for a Mac OS X and iOS app as well (so things such as icons for example). Has anyone here ever partnered with a designer to implement a business idea? If so do you have any hints and tips?
