Hi!
Yes we do offer 50 and 100 ETH packages via a separate smart contract.

You have to email us the expected amount and we will send you back the private smart contract. The source code is in our github and verifiable on Etherscan and is automated so
you receive ARX immediately

We had 3 private sales previously under our presale round so we are experienced with this method also.

We offer a small commission on the 100ETH package if you are organising it for a group, we will offer you this incentive,
Please reach out on staff@aronline.io or travisroe@aronline.io (or any of our other staff directly, but best to come via me for this) -

Cheers,
Travis
