Although the vast majority of designers are honest and hard working people, there are some things to watch out for to make sure your experience is a good one. There are some phony designers who might make bold claims but who are simply amateurs that will over promise and/or offer cheap prices but inevitably they will under deliver with crappy work and/or drag your project out for a very long time. Another concern is that there are many designers who claim to be qualified in areas that they only have minimal knowledge on. Choose your designer carefully and voice these problems by checking their portfolio thoroughly. But be careful I’ve even seen some designers go as far as claiming other designers with better quality work as their own.
