Totally depends on the employer and what their insurance is comfortable with. You can typically rely on any multi job (some Aztec LiDAR flying out there) will be around 50ME required. I've seen many jobs that are posted requiring 500 hours, but there's wiggle room. Just apply to everything and be okay with getting some no's. Also, look into Keystone Aerial Surveys when the hiring season for survey picks up again. I'm pretty sure their minimums for the entry level SEL jobs are pretty low.
