It is hard to have a standard price. Because some have bigger farms and request only contours others have smaller farms and request more products (or I offer).
This is one thing another thing is what data is available.
Do your area of interest has LIDAR data?
What is the level of processing level of the LIDAR data?
Depending on these factors I can asses how much work would be needed from my side.
But to make it clear and simple the best would be if you could send me a KML file with the extents of your area of interest and what products are you looking to get. This way I will check analyze available data and make workload assessment and than I will get back to you on email with my proposal.
- contours 2 ( foot interval) format KML or other as you wish
- digital elevation model
- aerial imagery
- drainage with streams and watersheds
- ridge lines
etc whatever else you will need and I did not thought about it.
So I wait for your email at firstname.lastname@example.org
