Rough cost of extending roads and utilities

[Account Closed]

First - I know the cost on this can vary widely, I'm just trying to get some kind of ballpark here. I have a lead on some acreage which is connected on two sides to subdivisions that were put in 5-10 years ago. I've been in the process of moving into new construction, and do not have any kind of pricing on costs to extend roads and utilities, not something I've come across yet. This particular property appears to be feasible and owner has realistic price in mind, so I'm just trying to get a ballpark to help with my initial offer.

If this property was built out the same way the surrounding areas were, there would be about 1500' feet of road and utilities needing to be extended, city water and sewer, gas and electric. Being a newer area, recently added roads are already built up to the edges of this property and blockaded- 30' width, with curbs and sidewalks. Area is relatively level, nothing out of the ordinary about the lot. Would anyone be willing to give me some idea of what price range might be, like a ballpark per linear foot?
