A company that sells swim spas but can't do the delivery? Hiring a crane is one thing, but I would think that a rep from the company would at least oversee it, connect the straps, etc... From what I have seen, subcontracted delivery crews typically don't provide the knowledge and service that in-house crews do. In-house crews also tend to care a bit more. I'm sure that there are good ones, but I would wonder why the company doesn't do it themselves. I'm not saying that it's a deal breaker, more of a red flag that warrants asking a few questions about who does the delivery and what the arrangement is. It's the same thing with service. If they subcontract it, I would want to ask a few more questions.
