So I am bisexually and already like looking at beautiful women. Gosh. I've done threesomes outside of providing, but I would actually like to offer doubles. How do I approach this? Email a random lady I think is gorgeous and just ask? Would love for a provider who have experienced doing doubles to enlighten me.

Personal sites,
Screening sites,
Review sites,
Advert sites.

In my opinion, providing them upfront helps lessen the leg work for making sure you are like, legit/established & stuff.

 
Get it, mama!

That will complement your style and work ethic. Don't necessarily need someone with a similar body type because guys like variety. Someone you can be comfortable with and have a genuine attraction to because a threesome with two ladies not really into each other sucks. Always always always meet her first and see how you mesh, I have been surprised before and learned my lesson! Most importantly have fun and enjoy the hobby, banging hot chicks for free while on the clock  works out fine for me! My doubles partners are too notch and we have real passion for each other, so it's always an explosive time and we are always eager to our next playtime/ appointment.
