Some things you have stated are not real clear to me. Is this a debt case (are they claiming you owe them money)? Are you asking them to provide you with proof of the debt? Do you owe the debt but disagree with them about the amount? Have you used goggle to look up the Rules of Civil procedure for the Court you are in?
First of all stay calm as you deal with all this. You are not dealing with a death penalty and you will survive all of this.
If you feel that you are out-gunned which you may very well be in that you are going up against what may be or become a stacked deck, then, what you have to do is play for time by reversing your strategy, in part.
Since they want to move fast on this, what you do is slow it down again by Filing a Motion and Order for time to hire attorney or Motion to Continue and/or Reschedule Hearing the ground are that you do not understand your rights in this matter and that you have contacted an attorney but are not sure if he will take this case and need more time to hire an attorney.
Be prepared to move forward in case the Judge denies your Motion but this will also serve as grounds for Appeal in case he grants the Summary Judgment. You are entitled to know your rights and hire an attorney there is no law against that yet lol. The other side will counter that you have had plenty of time or more than enough time to hire an attorney, therefore, you can take the position in your Motion that Plaintiff's most recent response (whatever title they gave it) has now made you aware that you do not have sufficient knowledge of the Rules of Civil procedure and laws to proceed with this case pro se (on your own) hence, you are asking that the Court grant you a reasonable time period to hire a competent attorney.
If this Motion is strong enough the Judge will not hear the Summary Judgment issues at all and will continue the matter to another date.
You can find out from the Court Clerks office or possibly the Judge's secretary etc. (some Courts have pro se people there to help others don't also the law school may be able to help) what Form of pleading they will require to be filed basically it's a simple Motion and Order for the Judge to sign continuing the matter to a blank date. Some of the Court people can be a pain and the standard answer is 'we can not give legal advice". You are not asking for legal advice you are asking a "procedure and/or process question".
So, it's either the attorney you have contacted files an Entry of Appearance and Motions the Court for time or you Motion the Court for time to get an attorney.
As you wade thru the Judicial process both process and procedural issues arise from time to time and the foregoing observations are of a generic nature relative to process.
