Suggestions for theme or plugin to manage RV Park

Hi. I am trying to help a customer manage her small RV Park. Can you help me find a WordPress theme or plugin to manage guests, rental spaces, scheduling, expenses and revenues?

On the back-end, the RV Park Manager would like to:

  • create or import records for her hundreds of previous Guests.
  • manually approve a reservation that is booked online, as no money will be collected online until the Manager is happy with the overall system.
  • record her expenses and revenues and print reports of those transactions. Her expenses are typical for such an endeavor. Her revenues include Space Rental fees and the sale of propane gas (she refills propane bottles).

On the front end, we would like a visitor to the website to:

  • see a map of the RV spaces, both available and not available.
  • book a space without making payment.

We are not interested in a subscription service where we are billed per reservation, or a hosted system. This is a small project with limited funding. The people using this system are novice computer users, so I must keep everything within easy reach. It should be mobile-friendly.

Thank you.

You will not find such things out of box.
