Returning to art - advice needed on setting up basic painting studio

[StellaBlue]

Hey, everybody!

I used to paint. And do papier mache. And screenprinting. And pen and ink drawings. And other random art.

And I want to get back to it. I have only ever painted in acrylics and watercolors, but I would like to paint in oils.

My question is: what do I need (I am on a budget!) to set up a basic oil-painting studio? I have an easel, but that's it! And where can I get canvas in a small town in East Texas? Do those of you outside cities order stuff in or what? When I used to paint, I made my own canvases out of separately-bought canvas, gesso, and clear pine, but I don't have the hardware to do that now. No saws, etc.

Thanks for any input.
