Depends really on what you want.
I can work to any budget, but you get what you pay for. Don't expect flash banners and loads of custom image slices for $100AUD.
Something like my site I would be charging around $400-$500AUD for, and hosting would be up to you. I am using free hosting for the time being, since I'm pretty much broke right now haha.
Not sure what country you are from, so maybe we need to work out what the exchange rate is first before we commit to anything.
