Public school grade?

Hey everyone, I have 6 elementary schools and 1 highschool in my small town. I was asked by the gym teachers if I would consider patch jobs for their gym rackets.

They are your typical steel $35CAD rackets, nothing special. Meant to take a beating.

Is there any strings out there that are cheap, come in a reel that I can do patch jobs with?

I had a friend recommend a HiQua string, it’s a 400m reel instead of 200. But I honestly don’t know where to go or know how to judge the string online.

Anyone have suggestions that are available to get in north America? BG65 string would be probably 10x better than these strings and a waste of my money.
