Vanilla guys are WAY too flaky and really often don't know how the "lifestyle" works. Most can be freaked out at the idea of the husband being involved at all. Vanilla guys do better if they think she's cheating. Our recommendation is to join a REPUTABLE lifestyle site and vet your guys through that site. They will have validations and you have many to chose from. You can chat with them before hand and get a feel for those you wish to pursue and (most) whom you do not. Lifestyle guys understand the deal if they have experience and they understand the husband being present, those things you guys like to do and that you want to take videos and pics. PM and we can give you a recommendation for a site. NO, we do not have any involvement in recruiting or making money off of a site.

EDIT...BY ALL MEANS AVOID SITES LIKE DOUBLELIST, ETC! There's a reason those guys aren't on a reputable lifestyle site. After you guys have enough experience then you can take a chance at finding a gem on hookup sites...but you really want her to have a great time with an understanding and respectable guy. An organic meetup (bar, party, beach, etc) could be fun but those rarely happen. You want a guy who respectful, SAFE, etc. Guys who have given their info to a lifestyle site are far less likely to be some sort of violent sex criminal, etc. Our opinion.
EDIT2...Also, free sites are likely to catch all sorts of curious guys and gals...your friends, your family members, co-workers etc. If members of a site are required to give information and pay (we don't even have our profile available to "free" members, then you're far less likely to be found out by those whom you don't care to know about your secret. If you do run into somebody you know on the site, they are there for the same reason.
Cathy is correct though about certain situations meeting a guy at a bar. If your wife is traveling on business or you are on vacation, at your hotel, the hotel bar can be a jackpot. Tougher as a couple though, but if you're outgoing and not shy, it could work well.
