Please help!! I am getting increasingly nervous/frustrated with this whole wedding planning thing..lol. I have been engaged since January, and I have not accomplished anything wedding related except for buying my wedding dress.

We were hoping to be married next March, and no later as I didnt want a summer wedding. I had my heart set on the Miami Beach Botanical Gardens, but since their renovations, their prices have tripled and are no longer in our price range. I want a beach wedding and perfer a low key beachy reception. Its not going to be a large wedding, 80ppl tops. I also didnt want to have it at a restaurant, as we would like to have an area where people can dance.
Here is where I need advice/help! I need to keep the cost of the wedding down as much as possible, so no more than 10K. I am willing to look at any location from Ft. Lauderdale to Key West. I am seriously not that picky as long as the location is nice

I am to the point where I think I need some kind of wedding planner to help with finding a potential venue, any reccommendations with that is welcome as well!
TIA!!!
