I know you're not looking for hosting for yourself, but asking because you're thinking about getting involved in a business that may be providing hosting services to adult webmasters.
Unfortunately you may be going down another bad road with this one.
You mentioned having the "opportunity to start a webhosting business" and the point I'd want to make to you is that there is absolutely no shortage whatsoever in available hosting providers, and there is very little demand for *new* web hosts. Most adult webmasters prefer to use one of the well-known, proven reliable hosting companies. Particularly after being burned a time or two by some new host which lured customers with low prices and big promises.
What successful adult webmasters need is a hosting company which knows *more* about hosting than they do. We need hosting run by people who understand exactly what we're talking about and why we need what we need. It's important for a host to have a staff which knows the languages we use to build our sites and understands the interaction of the various scripts we install.
And then there are the needed and almost constant upgrades to installed scripts, and updates to programming languages and to server software, and how those things may conflict to bring down some customers' websites. Plus the non-stop attacks by hackers and 'script kiddies' who hammer on hosting boxes looking for the smallest mistake in a configuration that will allow them to gain control of a box and use it for their own nefarious purposes.
If you have no background in being an adult webmaster, or even a successful mainstream webmaster, and aren't trained in the technical aspects related to hosting, or didn't grow up trying to hack into every network you ran into, then bringing only money to the table will not give you any competitive advantage to capitalize on. And if you're still working with the amount of cash you mentioned in your other thread, then you won't be capitalized well-enough to compete and win.
Nice to see you're still looking for a way in. But if you want to put your money to work without knowing the ins and outs of the business first, I'd really advise you to look at something besides providing hosting as your business model. (Unless of course you're buying in to an existing operation where you'd have an incredibly talented and knowledgeable partner and a first-rate support staff -- but I haven't heard of any of those looking for partners/investors, and there are only a very few that meet that criteria).
Good luck in your search for a new business.
