I wouldnt pay no more then a G for anybody. Jacka wonts 2,000 and 90% of the verses he have on other people shit be recycled or a brand new 8 and a recyled 8.
I wouldnt suggest going threw somebody manager either. The artist might wont a g and thats what the manager wonts to. Managers dont manage for free.
If you can have a sit down with artist or catch them at the club. Have what all these rappers love and caint say no to(Purple,white girl,thizzles). Also try buying drinks and chopping it with artist. Let that nigga know where you coming from. It dont hurt to spend a 100 and try to save 500. I will tell yall it dont work all the time.
