Give examples of the type of work that you are looking for and get quotes appropriate to the project. It's not the designer's "job" to convert your fucking traffic. Get a fucking clue. It is their job to provide you with a brandable layout, effective graphics, and usability for the surfer.
There are no "STATISTICALLY VERIFIED" design layouts or concepts. There is only popular opinion or creativity. Innovation tends to lead to better conversions. Following the crowd tends to lead to mediocre / dependable results.
Test your own fucking projects. The "Designer" takes YOUR input and produces the result. So, if the work doesn't convert... I got 2 words for you... FUCK YOU! Next time, give better details before you hire the designer. If you "accept" the final project, it's in your lap and up to you to make it work.
Moral of the story, hire someone based on their reputation, and quality of work. If they happen to be priced low, GOOD FOR YOU... You should stick with that 1 designer. If they are priced higher, at least you know that you'll be getting quality work from them... after all, YOU picked them.
