Starting steel erecting business

Hello all, I am new to the forum here. I was an ironworker for about 12 years before I started a residential remodeling business. Only a year later, I want to go back to hanging steel, under my own llc so I've been on the phone looking for work. I've got my first big building opportunity and I've spent the last few days putting together a bid. I'm trying to find someone willing to help me out and see if I'm somewhere in the right ballpark. I have 2 weeks to place my bid and 4 months to put my team together if I get the bid. As you can imagine, I am more than nervous/anxious, any advice of direction/guidance will be highly appreciated and with great appreciation comes gratitude.
