I believe I am good enough to be a website designer, but I'm more or less worried about offering my service. I have a good knowledge of WordPress Themes and general portfolio sites. So is their any chance some one could go through with me what you would go through in a general sales. Thanks.
You need to exude confidence! Having a good portfolio is obviously a good idea, as is a high-quality website (this is what you are offering people after all!) Closing sales can be tricky, depedning on the complexity of the brief and the type of client. I would be happy to critique your work if you like.
