Advice/Help needed! Unlicensed venue etc

I'm really struggling to find a venue for our ceremony. Basically, my fiancé and myself are booked for a big dream wedding next October but now I'm not sure I want a 'big' wedding. We now want to do the legal bits with two witnesses in a registry office and then either the next day or following week, we have a small unlicensed ceremony where we can exchange rings and vows in front of family & friends (we would consider this our wedding day, not the day we signed the documents). I really don't know where we can possibly hold such a ceremony, I imagine outdoors but can't find anything in shropshire?! We want to keep costs down to a minimum and have a intimate party with a BBQ/finger buffet but we don't know anyone with big enough land etc. does anyone have any suggestions? We want to go to New York next October as a honeymoon so we really don't want to spend thousands. We only want something small to celebrate with close family & friends. Any help/advice much appreciated
