Finward = Fg
m1 v^2 / r = Gm1m2/r
v^2 = Gm2/r
v = (square root of) Gm2/r

G= gravitational constant = 6.67x10^-11
m2= mass of earth = 5.98x10^24
r= radius of earth + altitude of satellite above earth = 6.37x10^6 + 1000 ?????

If everything else is right, would this equation give me initial velocity or average?
