Make use of other people's services. There are a lot of people out there willing to assist you for free. Just because they like to do it. Or to get their name or a link on another site. I have often seen pages of graphic designers, that make free banners or logos for non commercial sites.
Some software has wizards for making buttons and banners.
Think about Websuite, Netobjects Fusion, Microsoft Image Composer. Copy writing is not everybody's line of work. If you are troubled by this, ask someone else to write for you. If you want to do everything by yourself, take the effort to learn to use the necessary software. Surf the web and study sites on web design.
