Only estimator civil 4 yoe

I recently became the only estimator at my company that does civil work (40m/yr). I’m basically the only person who has a clue - having to argue with owner and PM’s that yes cost tracking is critical, yes production tracking is critical, yes tracking and applying overhead to bids is critical. GM is a nepo baby and I’m the only reason we have any work

I have 4 YOE, about a year as PM/E with really only 6 months being strictly estimating. I was PC before that who did both PC and estimate under our former chief estimator. I want to move to a bigger city and to a bigger contractor where I can work under someone more experienced and not have to fight for these basic things to be standard. yet every time I’ve applied anywhere, I don’t get an interview. what do I need to know about moving? nobody will take me seriously for anything other than PC roles

I’ve dialed our costs so that we’re are 2-3% off (or less) on public tenders up to 20m, and when the GM tells me back off productions, and we lose, I show him how we could have won using my numbers. I’m literally the only one who is trying to push the company forward, and I’m over it.
