hmmm....
If you were going to do this then you may want to target a more "mature" audience. Say people 35 to 55 years old. They have some assets put away, may own a home, been through a divorce or widowed and are lonely.
I did this for awhile BUT I became discouraged with the quality of service by the dating sites, themselves. They tend to hurt their income and mine by requiring people to join their membership BEFORE they can respond to a PAID members inquiry.
It makes sense on paper. You would think you would double or triple your business because people would pay to respond to someone who sent them an email. However, that's not the way it works in real life.
In real life PAID members expect to communicate with ALL members, paid or not. That's what they're paying for. But when they can't communicate with someone they find interesting because that person is a free-member then they become discouraged because more than 75% of any dating site is made up of free members.
Free members don't want to pay for a membership to answer one inquiry. And if paid members only inquire about other paid members then the free members drop out.
In any case, it's a bad business model but try explaining that to the dating sites. They deal in volume and don't care if you make money or not.
If you can, I would recommend a site where paid members can communicate with all members. And, I would target older adults in the 35 to 55 range or a specialty area such as swingers, bdsm, alternative, master/slave, etc...
Still a good market and income producer if you can find a good dating site to represent. If you do, let me know.
