You would also need to purchase a ring. And, I would assume that you would need to purchase several rings in the event that you were to ever travel or one just become damaged somehow while on the road.
You've also got to consider the amount that the venues would charge in order to use their facility. I'm sure outside of that they might also get a cut in the merchandise sells (if there is any) and advertisement on television.
I have no idea what it might cost to air a program like that on television but, initially, you would probably have to air a shorter program (maybe thirty minutes).
I don't have a clue about the ring attire issue but not very many women would probably want somebody telling them exactly what to wear. I guess a deal with a company like "Venus" would work but the only thing (after looking at their website) is that you would want to be like WOW in the way you go along with gimmicks. In other words, unless she's portraying a lifeguard, swim wear model, model, or just some type of "beauty-queen" or "LA girl", a one-piece or a bikini won't fit her gimmick. I can't see somebody portraying an educator, cow-girl, somebody from mythology, or a business woman dressed in swim wear. And too, if you have a deal like that, they might get part of the profits because they would want to be mentioned on the program (I'm sure) in some fashion. However, that would probably be an ideal kind of deal because, in addition to the regular male audience, you'd probably attract a large number of females (that could be advertised to).
I'm not sure you are accurate about the whole "people being more accepting in the 80's of certain situations than they are today". You'll have some parents that might be pissed with situations that really don't seem that bad but, regardless, I think most people are understanding of the fact that it's fake. Now, I'm not quite sure what would make a woman that attractive want to take a hit like that from an "old man", but it's probably really good money (which is the part you'll really have to worry about to find somebody and keep them on board). Back to the 80's and today, though: Did you see some of the things Stevie Richards did to Trish Stratus during that feud she had with Victoria? Or what about all of the times Team 3-D low-blow Gail Kim or other women on TNA? If anything, that proves that people are just as accepting of a woman taking a "low-blow" (or other attacks) from a man today as they were in the 80's. And, sadly, it's probably more accepted today than it was then. I think on some issues (that belong in the pit) people will always be non-accepting (I know I am) but what happens to a girl in a wrestling ring (no matter how dastardly, mean, or whatever) won't top many lists -- other than the parents of some kids.
As for airing it (again), you might also want to consider setting up a website with profiles of the wrestlers and talent and information (and possibly even a web-show). You'd want to make plenty of people aware of the product.
And, most importantly, before even starting something like that, you'd also probably want to have a fair amount of cash on hand and a business plan. Oh, and you can't just throw the women into the ring untrained -- they'll need training so they'll know how to take the punishment.
