Probable scam thru paymaya account

Good day I've been receiving messages from nigeria trying to order portable gas station from me and he said that he will give it to her sister as a present. Now, he is instructing me to do this,

Client from nigeria: "Sir my account manager said that your maya maximum balance must start from 5,300php Before the currency can convert your maya balance must start from 5,300 pesos, that’s why you don’t receive it immediately you authorize it

Try to cash in 5,300 to your maya now and leave it there until the $9,882.00 convert to 580,000 thousand pesos and add to it"

Me: I'll ask someone to confirm this transaction

And also I didn't gave my bank account information that this could be probably a scam.

Any thoughts?
