Basement Interior Design

Hello
I have 1 basement with area of 250 sqm
I need to create a floor plan with the following

1- living + dining area
2- office room
3- warship room
4- Guest room
5- small gym (could be integrated with office)
6- Game Room
7- Theater/cinema room
8- Storage

Please let me know if possible, and let me know if you need to remove any of the above

the 2 white stairs they still don't exist, please let me know which one suits the space better and I will do it accordingly

Please let me know the price and the required time

Many thanks
