My beach house fell through!!

I need a place to rent from Sunday the 14th through Fri or Sat. My sister and a friend was supposed to stay at my cousin's house at Mexico Beach and another family member has it!! It will 2 moms and 6 kids from ages 4-8. Not looking to spend more than 800.00. I know this is a long shot but if you have a rental not rented would you please consider us?!! 2 bedrooms off the beach is fine because kids are so small they can sleep together!!! Message me offline if you can help!!!!
