In your current design you only offer personal membership, here is a suggestion to that make a split to allow business and [personal memberships with different pricing availability for business and personal levels of membership.
Business will pay more for access to websites than a personal membership. When a business can market to members of a website it does attract more members. Make it where your business have more use of features per membership level they select to use.
Get out of the one sided websites that are stuck with limitations to offer service to members. Make is where more people join the site(s) as a social network while dating still has room for more members. Some people may not join a site if it has limitations, where they would be more appt to join if the could do business at the same time as dating.
