Most places that rent tools - like the saw you'd need - will also carry diamond blades, if you want to do it yourself.
You might try calling a concrete company, grading company or paving company if you want help with the sawing itself. Most all of them have the tools to do concrete/asphalt sawcutting. They also normally do free estimates - so they should be able to evaluate whether or not sawing will be the solution... and if so, how much they'll charge you to get 'er done.
