I have been granted a judgment, close to $1,000, against a business entity in PA. The judge certified the judgement and I entered it with the Monroe County court which the defendant received a notice of entry of judgment from the county.

I know the defendant's bank account and bank information which I would like to proceed with garnishing the account. The next step is to write a Praecipe to instruct the sheriff for garnishing the defendant bank account. I know how to do that. Then, the Writ of Execution comes to the picture. My question is:
Who prepares the Writ and notice of Execution? Should it be prepared by plaintiff (me) to submit it to the sheriff? Or, Sherrif with prepare the Writ and Notice of Execution upon receiving my Praecipe to deliver it to the defendant.

Please advise
