Alernative might be to look at direct Almeria to San Juan bus route (actually A/C coach). Not frequent and thus may not be a good fit to flight arrivals and would require getting from Almeria airport into Almeria city.
This coach however also calls at Los Gallardos so possibly could use Exclusive Almeria to Mojacar airport shuttle as mentioned from Airport to Los Gallados and change there but may involve a wait.
Websites for both services are:

Good luck with your trip.
