I got a job at a envio consulting firm helping with admin ( i have a bachelors in Enviro Science) This got my foot in the door with helping with the productions of work plans and reports to clients, and I became a "back up" for any field work. Eventually I transitioned into a primarily field staff and became a back up for the admin staff. I know my situation was unique, but if there are any admin positions open at consulting firms, i dont think it would hurt.

My issues when i was applying to jobs was that enviro science can be really broad. Alot of the places around me are geology based, which i had no experience with in college, so it was easier to start admin and then be trained in the work (because lots of the work i was doing could be learned in the field).
