Solving PDE (how to introduce an specific Boundary condition)

Hello,
I have some troubles when trying to solve for a second order PDE. Would be wonderful if you can help me.
The PDE I want to solve is the following:
uxx + (2*y^2)*uyy + (1+0.3*x*ux+0.5*(2y)*uy) = 0.3*u
defined for x>=0 and y>=0
and with boundaries: u(0,y)=0 and ux(y,y)=1
( where u denotes the function to solve for u(x,y); ux is the first derivative with respect to x, uy the partial wrt to y, and uxx denote second derivatives).
My first trouble is with the boundary condition: I am using the pde tool, and I don't see how can I implement this boundary condition in the options of Neumann or Dirichlet available.
Thank you!
