Modify existing wall oven cabinet to fit standard size oven

I'm after someone to modify an existing kitchen cabinet to install a new wall oven. The old wall oven has been removed, but the hole is not the standard size. It measures approx. 670 x 770. It's an old kitchen that will be replaced in a few years so it doesn't need to have a matching finish, just needs to allow for the new oven to be installed. I would be happy with a plywood finish if that helps the cost.
