I am interesting capturing boudoir photos of myself, so I would need something that can set off the camera remotely, a remote or something.

I don't really have a budget, but don't want to spend extra hundreds of dollars just for small upgrades in the quality.

It did some looking around and it seems that the best bang for your back cameras are around 1500-2000. I realize that I would also need to have other stuff too for lighting, lenses, etc.

I have zero experience with cameras but am very interested in capturing my physique.

If I can also use this camera for regular professional and dating profile photos, that would be a bonus.

At the moment, I am only interested in doors. I also travel often and would like things to be portable enough to take with me on trips.

From my research, mirrorless full frame cameras would be best.

Budget: 

Total, including everything (camera, lenses, lighting, tripod, whatever else I need) Around 4000 USD. It seems most bang for your buck cameras are under 1300.

Country: 

USA

Condition: 

Prefer New, but can consider used

Type of Camera:

Mirrorless , full frame

Intended use: 

Photography mainly, but am also planning on getting into video, though I was assuming may require another camera.

what style

boudoir, indoors for now, planning on outdoors in the future. Bonus if it can be used for dating profile pictures.

Features

I am not familiar with these, but perhaps anything that helps with self taken boudoir. So perhaps autoofocus, face finding, etc. Being able to set a capture via remote. Being able to connect to phone or laptop so I can see what's it's capturing in real time. A way to flip the screen so it's facing towards me would be good not not required if I can use phone/laptop

Already considering: 

Just looking at the pages that come up for 'boudoir camera', here are the ones recommended that are best bang for your buck, EOS R6, Canon EOS R8, , Sony A7 IV, Fujifilm X-T4, Sony A7 III or IV, Panasonic Lumix S5II, Fujifilm X-T3, Nikon Z50, Sony A6#00.
