Show him what needs to be done. Do a simple web design base on my layout. Agreed with the price. Then he anyhow just do it. Ask him about the design, he say need to pay extra to design. There is no design just do my layout follow my theme which I have sample and css ready to copy. Make text proportion not like children's work. He say his job just paste the element of the form on the page only. Then might as well I do it myself why get a web designer.
