Yes.
You have.
He's a hire. Not your boyfriend.
His actions are pretty clear signals that he doesn't want a personal relationship. It's not clear if he'd be open to continuing a professional relationship as long as you learn to respect some boundaries.
Like they say: "read the room".

It just works best if you're looking to have some naked fun while easily being able to keep track of trouble.

Yes, it's very common for providers to forget to renew their ads right away. Especially among the flakes.

I know some providers who regularly use the “Not Available” function, bounce from Basic to Gold member on RM, and sometimes take breaks where they don’t advertise for a month or two. All for different reasons. For some, they tend to advertise during higher seasons as it’s more of an occasional side gig. Others sometimes run into financial difficulties making payments on time. 

Has the conversation moved off RM and by text? I agree with the others here and think that a nice “Hey! One week away! What’s your schedule like to make firmer plans?” could help you see if he’s on top of his stuff. 
 
If he seems unfamiliar with details that were previous discussed, extremely slow to respond compared to previous response times, and unable to make you feel confident in meeting, I’d say look for another provider. At the end of the day, you want to make sure you don’t have to spend your time travelling scoping new providers and trying to find one you connect with. 

One of the guys I hire regularly told me he was deactivating his rent masseur account and only continuing with regulars he has.  He contacted me so I knew that and didn't think just what you are right now.  I agree, just reach out to him.

Not necessarily - check with to confirm. I pulled my ads for about a year when I was diagnosing and going through being diagnosed with MS and it all got to be too much. I still have my regulars despite not advertising as much. 

I have numerous "types," but one of them is the "boy-next-door" / "man-next-door" who is rather clean cut. By clean cut, I mean neat beard and a few tattoos at most. No PNP/extreme alternative vibe. There seem to be fewer and fewer of those kinds of guys out there these days. Do you have any suggestions of tops or verse tops of any race/ethnicity or age range (24 or older) who might be worth checking out?

If you shop on RentMasseur, that site is overwhelmingly gay men advertising to gay men. I always pick a masseur who advertises therapeutic, sensual and erotic. I always go to independent masseurs, not a massage parlor. First and foremost, I want a good therapeutic massage. I carefully read the reviews and look for 5 star ratings, and descriptions of an excellent therapeutic massage. I am also looking for a masseur where 90% of the reviews  were for erotic massages. That indicates that it's  a good bet he expects you to be nude and also expects to give you at least a HE in addition to a therapeutic massage. When I arrive I am super friendly, maintain direct eye contact, get out of my clothes immediately, as we are talking, and walk around naked (go to the bathroom etc). It's called flaunt it. The best masseurs give a great massage, introduce sensual elements throughout, and progress to a great erotic experience sometime during the session. Some will start out in shorts or speedos, but many don't. Also, I have found the more often I see someone, the more connected the whole experience becomes. And let's face it, gay men connect through penises.
