What is the price? What are the region and instances limits? Do you sell the accounts together with emails they are bound to?
I advice everyone to read some basic infos about AWS accounts and how to avoid scammers, link in my signature.
You have basically no positive trust feedback, in fact you have multiple negative trust feedbacks.
I'm talking about creating AWS accounts from scratch based on whatever anyone needs. I'm not asking for money in advance, I'm not asking to work without escrow. I'm offering for the buyer to have the account credentials first hand and upon satisfaction I get paid. I'm not promising to work some magic and provide accounts in bulk within days.
I'm interested in working with people who know what they want and are willing to be patient for the quality they need.
In addition to my previous post I strongly recommend to not pay this seller until at least several days after you have received the account and, if possible, not before the next invoice is issued by Amazon. You can easily time both together, e.g. receiving the account around 25th and paying around 5th next month.
Also notice that
the seller absolutely and intentionally ignored each and every question I asked. This case is closed to me.
