You can start by going to www.narpm.org and search their directory of managers.

Submitted business information to directories.

Is there a directory of 1031 exchange service providers anywhere on Bigger pockets?

Sometimes local real estate associations will list them that way in directories, but ultimately, investors just need to know how to ask the right questions when they're looking for a realtor. 

Many cities have good online directories of residents as well.

@Collin Goodwin Here are four options.Build a Mobile Home Park property management company from the ground up - cold call MHP owners (MHvillage.com has a comprehensive directory) and see if any of them are tired of managing their park (there will be plenty of people that say yes).

Is there any type of website or directory where you can reach wholesalers in New Jersey other than Bigger Pockets?

They basically curate information that already exists in a way that makes it easier to absorb.

Call them or take a look at the information provided on their website.Here is an example of hard Money lender that did a great job at providing the information on their website.https://www.abl1.net/loan-programs/fix-flip-hard-m...If you want to be quick at getting the info, call them.But there are a lot more other hard money lenders.You can find a directory of those hard money lender on BPhttps://www.biggerpockets.com/hardmoneylendersHope it helps

If for some reason they did not already have an agent within that distance you would want to make certain your office was visible (google, maps, local directories, phone book, whatever) should they be looking for an agent to meet the banks criteria.Of course this is just logic, but you would be amazed how many agents its actually difficult to find.And as a related issue - if you are an agent - you should be able to Google your name and find your number instantly.
