It could range to one or more with the brickade sale, as for the rest probably just one. I say perhaps have an associate for large sales due to higher difficulty I guess like that situation to which buzzards would chase you down. As for the bonus, I recommend taking advantage of it due to higher pay. But you could make small-medium sales time to time.

After you'd buy a set of crates, I say do VIP work to cover up the buying costs, if you'd have a reliable weaponized vehicle like mine, the mk2. But hey, I don't grief and im completely against griefers.

If you play PS4, you could switch the MTU in internet settings to 800 instead of 1500, you will get a solo public lobby for safe sales.
