As mentioned in the title, I've been offered a job to help build a pretty ambitious studio, in a kinda right time right place situation. The guy who offered me the job seems really nice but his other business is very unrelated, meaning that he's quite new to this himself. Only met him for a few hours, he just showed me around and we talked about a few ideas ect... He asked if I'd be comfortable with freelance, I said of course. But I don't know how much I'm supposed to charge for something like that especially if I've never really done it before.
I haven't built a studio before besides converting a walk in wardrobe into a small space for myself (terrible acoustics), my work in the industry has been as a sound-tech for a big enough venue for a year, a local crew for big arena concerts for a year, and I've a diplomat in music production. Despite feeling like I've not much expertise with this, I do feel like I could have a lot to offer, mostly in the branding and some D.I.Y stuff. I'm also pretty hard working and I'm very willing to learn new stuff.
I'm basically just asking you all for any possible advice you could give !
