Crypto cashout setup query

Hi guys,
I am from India, looking to monthly cashout ~20k USD.
I am thinking to cashout crypto money to fiat via banking channel with help of dummy business.
As per my plan:-
Setup an offshore company for IT related ( website design/ developer ) in UAE or Singapore.
This will issue random invoice for services and and me act as client and pay BTC to my exchange portal convert to USD and withdraw in offshore bank account.
Then wire to my India bank account as dividend and pay tax.
Is this bad setup or not ?
Do i need to prove my fund sources to my offshore bank/ govt. regulator...?

=> BTW my funds in crypto wallet and earned via p2p exchange ( unlicensed ) via some forums.

Hi,
Is your crypto gains a result of genuine investment in the crypto sphere or did they come about for other reasons?

Well some amount i purchased via bank, e-wallet but all unregulated.
I was doing exchange p2p So unable to justify fund sources.
But i checked my coins txn via AMLBOT and all in safe zone.
