I can tell you that planting costs can vary pretty significantly though. Gotta pick out the correct species for the area, what you want the seedlings to be able to do(mass/straightness/volume). Might have to take into account prep work like spraying or tilling if it is really crappy soil. Also have to spray a few times in the first 1.5yrs to get rid of competition. It would be best suited for someone to actually see the property, but I will try and get him to guestimate based on the area. What city is it in(soil types matter)?
Pine trees do have many graphs and whatnot, but it still isn't too easy. Hardwoods are more fun
