Replying to My boss wants me to make a commercial for him

he owns like this mini golf, go kart, bumper boating etc amusement place.

he's seen some of my stuff and likes it and now i am storyboarding it out and he told me we would go through it when im done and i can tell him what i want for it.

so i really have no clue what to ask for. I've never really been paid for making video before.

I was thinking $600 cnd. and his son in law who helps run the place and is really chill said he didnt think that was unreasonable.

I dont think I can go much higher than that but what do you think for a 4-5 minute video. with some graphic work and motion tracking titles and stuff.

here is some of my stuff so you can get an idea about how much experience i have filming and editing.
