Selling one of the most popular local FB Groups

I have one of the largest go-to Facebook groups with about 15,000 members. The group has been around for 5 years. On top of the regular content of the group, I also offer advertising to businesses currently (Either weekly or monthly) In the background photo & announcement section. Another really beneficial idea would be to market your own business through the group or advertise anything else that you want maximum exposure on. Radio stations also have been doing segments with it, and I have 5 active moderators. Interested in serious cash offers. Please only contact me if you are interested in what I'm offering. Thanks for reading.
