For viper blade sets you can go for Japanese Denso or other Brands. It will be around 4,000
I got Honda Genuine Drive Belt for 6,000 from authorized distributor.
Brand new Japanese Thermostat costed me around 2,500.
For Front Shocks I got RBI Mounting which is made in Thailand for 6,000 almost. It's working perfect
For the rest items the cost was same as I got them Genuine.
I can share receipt of work if you need for help
