If the plot is large enough you can hire someone to spread the lime. Lime can be cheap when bought in bulk ($6-40 ton delivered and spread) If it's small just spread it with the spreader or by throwing it around. The key to making it work fast is throughly mixing it in the top 4-5" of ground. If you mix it it will deacidify up to 5x quicker. If not it may take up to a year or longer. Lime doesn't move thru the soil it goes only where you take it.
