How to buy Crypto from US entity cheaply

[Alenka]

I want to buy crypto through US LLC with best possible rate, close to 1:1. I found that one of the providers offer to convert fiat to crypto for 2.5% + 60 USD for each exchange, are there cheaper alternatives?

P.S. crypto is going to be bought for business expenses, must be exchange that offer institutional services.

can't you open business account with Kraken another major exchange? it would be⁤ way cheaper...
