These subpoenas are not filed with the clerk. You or someone you hire needs to personally serve them on the individual involved (not by mail, fax, email, etc.). If it is a corporation, you will need to serve it on the designated agent for service of process (found on the secretary of state's website) or another person identified by the company. You can find the specifics of this in California Code of Civil Procedure section 2020.220(b) and (c).
You will also need to enclose the appropriate witness fee of $35 with the subpoena for production of documents (see California Code of Civil Procedure section 2020.230 and Government Code section 68093).
Keep in mind that if you are seeking the documents containing consumer information of a third party, you will need to give the notice to consumer required under California Code of Civil Procedure section 1985.3 and 1985.4 if the personal records are for someone other than yourself or the third party receiving the subpoena.

You should not be relied on any of this advice because each case is fact specific and could be subject to different local, state, and federal law. No attorney-client relationship exists based on this response.
The clerk will issue a subpoena at not cost to you. A copy has to be personally served on the witness. You hold the original with original proof of service, bring it to court with you. If witness does not appear you can show it to court and ask for an OSC re Contempt to be issued.
Depending upon the records being sought you may have to comply with provisions of Section 1985.3 in terms of timing and service on opposing party and witness.

If you do not have an attorney and ask the clerk to issue the subpoena, it is often still a good idea to have it served by a professional process server. The cost is $40 or so and they will provide a Proof of Service for you. It does sound like you will have to follow 1985.3 and provide notice so the consumer can file an objection to your ability to get the records if they want to.
