You created self-importance p2pkh-addresses prior to now, you could have entry to the non-public keys (WIF) and addresses (1…).

Now you need to spend the funds securely and in an offline method (you don’t want to enter your non-public key into an ONLINE pc).

I think about one thing like:

• You enter the p2pkh handle (ONLINE), this system fetches the UTXOs and
  creates a listing of transactions and an unsigned transaction
  to spend the inputs to a given handle.
• Within the subsequent step you may signal
  the transaction (OFFLINE) and export the signed transaction.
• Within the
  final step you submit the TX to the community.

Are there any user-friendly instruments/packages that supply this performance?
