I haven't been there in years, but several years ago a co-worker went and was impressed by the selection (altho' he found that the prices weren't much different from retail locations even tho' they are a manufacturer) at Capitol in South Amboy. The website isn't much help (Statuary- "contact us"), it looks like their main business is pavers and walls, but it'll get you there.

I know that this is an old post, but I would like to include my information in case anyone comes across this. Our company is located in Michigan, and we ship items across the country, our website contains thousands of products and if we don't have it on our site, give us a call; chances are we can find it for you. We've been in business for over 50 years. As for the company Capitol they have since discontinued their concrete statuary division, we have bought some of their molds and continue to make certain pieces.

Daisy Garden Center on Route 206 in Hillsborough has garden sculptures.

Fountains of Wayne. Pricey, but a large selection. (Note: Yes, it is the name of a band--but they took their name from this business, which isn't actually in Wayne, but close.)
