Without knowing "how far" your utilities will need to be extended from where they currently are to where you want your pedestal will change the the price you pay, a lot. Do you have a level area to pour your slab or are you on a slope? If it's a slope, how steep? Makes a big difference in your grading costs. Do you need to add drainage to divert water away from your slab? Do you want a paved driveway or gravel or ? from the primary access road to the slab? What is the bearing capacity of the soil? Is it expansive soil? Labor and material costs vary widely depending on your area. Any trees/large rocks that need to be moved? etc., etc., etc.
As you can see, there are so many variables that without more plans and specifications it is next to impossible to give you a meaningful price.
