My question involves court procedures for the state of: New Jersey

Hello. I own a piece of property in which I reside. I have a flag lot and a long driveway. I have 2 neighbors that have an easement to egress/ingress over several hundred feet of my driveway by the public road. Prior to me buying the property, the three parties signed a 'driveway maintenance agreement', only one of the original signers remains an owner. When I first moved in things were friendly, we talked about the driveway maintenance and the 3 of us agreed verbally we would perform the work ourselves instead of hiring contractors, however the problems started. One neighbor complained we didn't need gravel, one wouldn't show up to help work on it, etc. Now we are at the point neither of them participate at all. So I plan to do all the work myself and somehow bill them for my labor, tractor use, snow plow use, etc. I am not looking to get rich but feel they should pay their share. I predict they will not pay and will have to take them to small claims court. I am considering two options: 1. Get 3 estimates to show basic costs, do the work myself and bill for my labor/plow/tractor use which should be way less than if I hired. Would this fly is small claims court? 2. Hire 2 laborers to replace my 2 neighbors and the 3 of us do the work and bill them for the laborers. Would this fly? If I paid laborers cash how would I prove that? I would really prefer option 1 as I am on a budget and don't want to lay out money I might not get back. Also based on some NJ easement reading I gather since I own and use the entire driveway they have no rights to fix something, or hire someone to fix something or do anything other than ingress/egress? Concerned they might try and do something on my driveway and bill me. I understand if I let the driveway go in disrepair they can repair so its useable for ingress/egress.

quote from maintenance agreement: "the parties agree to equally share the cost of all necessary and reasonable repairs/maintenance for the right-of-way running from county road XXX to the XXX residence. Such costs include, but not limited to, purchase of stone, grading, snow plowing, etc. The parties agree that there must be prior approval for any single repair or maintenance that exceeds the cost of $XXX.XX"

So I am trying to find the best way for me to do the maintenance and bill them for my labor/machine time.

Also what happens if we need a repair I actually have to hire someone for and it is more than $XXX.XX and they don't approve?

Thanks, I appreciate any help I can get.
