NDSolve problem

Hello,

I try to numerically solve a nonlinear ODE:

NDSolve[
{1-5x-0.2V[x]-V'[x]+V'[x]^2+V''[x]==0, V[0]==V[3]-100,V[100]==-200},
V,{x,0,100}]

Mathematica returns:
NDSolve::inrhs: Differential equation does not evaluate to a number or
the equation is not an nth order linear ordinary differential
equation.

How can I get around this difficulty?

Thanks,
Owen
