LOW BUDGET WEDDING

HELP! I am recently engaged and am starting to plan this wedding. I dont want to spend thousands and thousands of dollars of this day. It is seemliy impossible to have this day cost anything under 9 - 10 thousand dollars. I just can't afford that and seem doomed to just go to the courthouse or something.

 Anyone have a super cheap wedding? How and where did you do it? I am so overwhelmed.
