Do you have a budget? This would be the first question I would ask which also relates to your potential. You are looking at 15-20k typically.

Then are you looking at concrete or a rubber base?

Be certain that this is something you plan to use for years and years as the ROI on homeowner-specific improvements are not very high.  Budget for the concrete work involved is usually around $15-20K alone, not including the poles and painting.  If you plan to sell your home in less than 10 years or would need the court for less than 10 years, don't do it.  A new upgraded entry way, minor kitchen update, interior room/living space addition or new Hardie Board siding will give you a much better return on investment.
