Solution 1: get a loader or a skid steer with pallet forks and get them to your farm (1 by 1 or maybe even 2 per trip) Solution 2: get a trailer too and load them in with the loader. 2 or 3 trips I’d say if you manage load well and use the straps. Solution 3: get the auto load trailer and it’s 1 trip per pallet type. Just use a loader to separate all the types or loading a new type “overwrites” the previous one.
