I am doing Facebook pages for Fiverr. A did a nice design and sent it to this guy. He is asking for a an image for the profile as well and also a "like" button at the top of the design What can I do not to get this guy to give me bad rep? Should i tell him straight up that it will cost more? I am already providing a hell of a service and he is asking for more. What a twat! Any advice would be great!
