Help! Website builder needed

HI there. Can anyone help me. I'm a self-employed business consultant
in England and I want help building a simple ish website maybe 6 page
but very professional looking nothing too complex just an enquiry form,
a map and text. I have a budget of ~£500 ($1000) to spend but I've
been looking for about a year and drawn a complete blank!

Does anyone have any recommendations for where I shoudl be looking??

Thanks!
