Dog Training Recs

Please send any and all recommendations! I have a 6 month old shih poo puppy who DESPISES his crate. He will bark relentlessly. He is otherwise an amazing puppy, potty trained, does well on a leash, with people, will not bite, etc, but will not stop barking if left alone in or out of crate. I am looking for some affordable services for crate training only in Omaha to help me out with this feat. He is not food motivated (or anything motivated besides being beside me), and I am not experienced in this kind of training, so I feel like I’m getting nowhere. Any recommendations of AFFORDABLE options that are affective and work quickly are appreciated. We live in an apartment and I cannot afford to have him barking all hours of the night and every time I leave for much longer.
