Taxi from the airport to Palma Nova for two passengers with luggage and two folding wheeled walking aids.

We have booked a last-minute break and need a taxi for tomorrow morning from the airport to Palma Nova. I have contacted a couple of taxi companies, outlining our needs, however, we have had no luck so far. We are two ladies with one large suitcase, one cabin-sized case, two under seat bags and two folding wheeled walkers. We need something like a large estate car, as we struggle to climb into a van conversion or a minibus unless it has a step. Any help or advice would be much appreciated.
