For $90 he better put more than 1 coat of clear.
If he'* a really experienced painter and could do it perfectly and you wouldn't mind paying for the convenience of having it done, then go for it. But you could always try yourself as there'* people here that can help you if you need it. If it doesn't work out then you could have the guy paint it. I took on painting for the first time (with the green one) and with a little practice projects I easily did whole fenders by myself with normal paint cans. A grill would be a good starting project.
