Hello,
we all work for a living, the rate you have put is too low for the requirement, It should be atleast 2000 USD for simplest setup.
I am having 20+ years experience, working as a consultant in Bigdata/IoT, I am certified in Cassandra , and have a master of computer applications post graduate degree
How big is your file and how big is your server(RAM/storage/CPU) how many node you are planning?
Feel free to contact me so that we can have a discussion
Best regards
Constantine Stanley
