I work with such projects at my workshop. I have Rpi, high speed cameras, LED strips, circuitory for controlling these, microphone and all. Not in exact quantities, but almost all. The BOM (bill of materials) as per my calculation of some good products will cost nearly 70k, and rest are working charges. For instance, 4 cameras will cost around 20k for motion capture quality. The Rpi will cost 8k for instance.
DELIVERABLES: Making a 6x13 installation and physically delivering it. Hardware and software to run it. Installation and demo. Based on your location in Mysore, it will cost 5k shipment.
PURCHASES
I have a workshop where we build such things, custom for customers like you. We can add and remove functionality. But, based on what you have mentioned so far, it will cost you more than a lakh. You also have to pay an advance, and send payment for hardware. The bills softcopies will be shared to you, during purchases.
In case you are interested, you can visit our workshop remotely, and if you are ok, then we can make a deal. Thanks!!
