Do any of the subscription required websites have many jobs for lowtime pilots? I'm still under 400 hours and I'm wondering if any of those websites like findapilot, climbto350, etc, regularly have job postings for 500ish (and lower) hour pilots.

Probably not, unless it's a for a CFI position at some small field in the middle of nowhere that can't find anyone local.

Anyone who wants a low-time pilot either has a stack of resumes or can just walk over to the FBO and ask for one.

Unfortunately, this is true. Save the CLIMB350 fees and just network. Browse flight schools online or Banner Towing joints and submit resumes or if there's a place near you walk it in. There's not too many places looking for a 400hr guy right now when there's 1500hr guys on the street. Good luck to you.

Thanks for the replies. That's what I figured , just wanted to ask around before wasting money to find that out.
