I have an old paper wallet (pre-fork) I would like to transfer to an offline computer running Electrum. I believe this is known as cold storage. I would like someone to walk me through this step by step. I have downloaded Electrum to my now offline machine and am ready to do the next step, but I don't know what the next step is. I will pay someone willing to hold my hand and help me through this entire process in a safe way.
