Well Kami, to be honest your going to have to work at it a little more first. The market/industry is huge, and everyone and their uncle claims they can design websites. Us designers are a dime a dozen, unless you have the skills.. and even then, there are SO many skilled artists.
Taking that website for example, the extra effort you put into with the evil eyecandy bevels and shadow, actually made it look worse. The minimalistic 2d/flat sort of frame look that was there b4 the bevels would have looked better. Less is more in this case.
Having said that, you could still get jobs.
There is no fixed rates. You have to charge what you feel they can afford because webdesign has and always will be pretty expensive.. the prices have only been getting higher and higher as multimedia and newmedia gets pushed farther. Animation becoming a standard in most websites doesn't help either.
I charge around $25/hr. Its hard to put a time limit on creativity though.. somtimes I'll sit there and stare, and sometimes I won't stop for hours on end.. it depends how the juices are flowing.
Things to take into consideration when settling your price..
-Creative Freedom - This is a big one.. so I'll just discuss for a second. There is two ways you'll be doing GFX for someone. With creative control, or without. If you have creative freedom then obviously you are incharge of all the cosmetics. Design/colours/feel/navigation, ect. This is EASIER because its not forced creativity.. its just, your work. If you don't have the freedom however, the job becomes a lot harder. You'll end up with many retries and variations to give them, since you are designing their ideas without their mind.
-Code? (Just html, or is there a code that actually requires some effort/knowledge, PHP?)
-Images (NOT graphics, did you have to scan images/take pictures ect, touch of photos)
-Graphics (The website itself)
-Content (Whos writing the content, you or them?)
-Animation (Even just basic imageready (gif) animation is still very effective if used write)
Blah, I can't think of all this right now..
Good luck, and keep at it!
