First of all you can't call it a business partnership when you are asking for 0% fees, that kind of business looks quite unfair.
Second is that PayPal transactions are reversable and you are a newbie. Which means that you may easily scam someone. Some paymentfor risk seems resonable. Also Sender should pay fees in BTC and they also cam be pretty high.
Third. People may have any other expences. Like they need cash and they are choosing between localbitcoins and you. If they will add % that will cover their withdrawal fees then they are fine with you. If no then it is more likely that your grand sons will keep selling this PP after you.
1: Some people want to cash-out their Bitcoins and I provide a solution
2: As PayPal you can send as friend, and these payments are not reversable
3: PayPal does not have any withdraw Fees, so what expences you mean?
Still looking for a serious trade!
Kind regards,
