Who is a weak-minded person who would buy a private key for someone's wallet in order to get the coins inside it and expose himself to losing the money that he would deposit if the wallet contains a malicious bot or DApp, I apologize to you OP but your intentions seem bad because this method is very popular among the scammers, therefore, I do not advise someone to buy the private key or recovery phrases from you, because he will 100% lose all his money that he will deposit in order to transfer or exchange Tezos and Cosmos coins.
