how can i build an attractive home theater for under $3500?

Hello. I need help coming up with things to get for my home theater. My budget is 00.
- My preferences include an electric 100"+ screen, and an Optoma projector. I also need a reciever, and a nice sound system.
- In terms of decor, I would like four seats (preferibly leather recliners if possible), attractice lights, and wall decor (maybe acoustic panels?), and I am able to get movie posters. I would like a curtian to go across the screen too.
- If someone could help me come up with a design, product list, it would mean the world to me! I cannot design for my life! Thanks a whole bunch!
- No more than 00!!!!
