Small to medium sized portable lighting system

[Deleted member 19071]

Thanks in advance of any help you can offer. Its greatly appreciated!!!

Ive got some portrait work lined up and will need a portable set up to take along. Also wanting something fairly reliable as its looking like if i do a good job initially i could get a lot more on the back of it.

So i watched this tutorial and it made a lot of sense: http://improvephotography.com/5862/understand-how-to-use-off-camera-flash-in-10-minutes-or-less/
Looking for something i can take to a room, set up in relatively small space like a living room to a hall if need be.

1. So a back drop, stand etc
   
2. flash units(more than one i presume?),
3. reflectors?
4. stands for flash units
5. triggers/receivers etc?
   
6. Umbrellas....
   
   Is that it???

I heard those guys say infrared was bad in sunny situations and to for radio triggers instead?

My camera is a nikon d750. Budget, well i know i can get light stands/mounts for flashes and umbrellas cheap enough but no idea on flash units and what i need to get them all working together with my camera?
Just one other thought, i could do with advice on rechargeable batteries i guess for a few flash units if anyone has advice?

Thanks again for any help, oh and im shooting in a couple of weeks for the first set so need something fairly quick!
