Logo design for camp

I work in a school and they asked me to rebrand their logo for their camp. I’ve already done a couple of real logos and monograms…
I just need to do the logo…no business cards or anything

Is $150 underselling myself for a school? Or is that normal?

It is a drop on the lower end but I think its fine as long as you are okay with it…
You can ask for $175 - $200 if you want more…
but I’m not really an expert with prices so try to get some more opinions…
