Japanese women have started to pay men for companionship and many to marry them as well.
It's a trend that started some years ago because the men in Japan have increasingly seen their Human Rights denied and/or abused by a goverment-backed female population who's become so demanding and mean that these guys just stopped dating and marrying altogether. They call themselves Herbivore Men and their philosophy dates thousands of years.
This is how bad it got. Now those same demanding women are having to pay for their company.
The Herbivore way of life has now reached the Western world and there is now large portions of the western male population who won't have anything to do with women if it's not in a proffessional setting.
See the book Men On Strike for more info.
The reasons are well known, at least to men and those who want to face the truth head-on so I will not enumerate them here.
Suffice to say that paying for male companionship will become common place in the West in a few years if Western women do not wake up.

So, OP, your idea isn't so weird. The only problem I see right now is that Western men aren't as philosophically advanced as Japanese men yet so you may fall prey to abuse and litigation.
