Thanks all for the sage advice. I've been able to come back with a sensible figure that serves everyone involved well given the job at hand. I would have lowballed myself otherwise. Much appreciated.
My mate also charges a kit rate on top of day rate, I think only for shooting days but it works out well - his stuff gets paid for over time and the production company can see a saving over hiring for the whole duration.
@cornelius_blackfoot Yep it'd be my own gear, which I factor into rate.
