While Most of the responses here are 100% accurate, there are other factors that you should consider that were not mentioned yet and are very important. The cost on average is $2000-$3000 but could chance based on the amount of survey work legal work, etc. I have been through this myself and you will absolutely need legal help and guidance. If you wish, you can give me a call and I can discuss with a few things that you should be very aware of before you move forward and start outlaying dollars..
