You better find a good duo partner that you can work and compatible with. 

Duo is fun Babe you should try and @adrianalwaysdtf is right, it's extra rate but it's really up to you. 

Offering duo means extra money. Also, if I'm not mistaken this service is expensive than a regular meeting.

It's not a bad idea to add this to your service. 😊 

I've never had a duo buddy as such
My question though is by having such a setup, will it generate interest/business? Or are they more hassle than their worth?
Thank you
