It all depends on where you live and how your utilities work. I've read posts from people all over the country on here, and it's amazing how different it all works.
In my part of the country, running power into a property is based on the load demand of that property. If you use allot of electricity, they take that into consideration on what they will charge you to install the power lines. Most residential installs will qualify for one pole about 300 feet into the property for free. Then it's based on the cost of wire, which varies quite a bit. If you go underground, the price is more because it's more expensive wire. You can only go so far at 240 volts, so you will either need to put the transformer at or near the house and run high voltage to the house, or you can have the transformer at the property line and run the wire from there to the house. If you do that, you will have issues with the distance. The farther you go, the bigger the wire you will need. Aluminum is allot cheaper, but copper carries electricity better. Then the trench may be something you can do, or not. It will depend on the supplier. Same thing with installing the wire. If you can dig the trench and install the wire, you can save allot of money, but that's only if they allow you to do this.
Phone is almost always installed by a vibratory trencher. They just drive the tractor from the box where the wires are connected to the building. In my experience, there is no charge for this, but I've never gone more then a 1,000 feet.
Septic laws are always changing. It used to be that a septic tank and leach field for a three bedrrom house was around $5,000 in an open field that has good soil in it. Dealing with other conditions or soil types can easily add allot to this price. Same thing with permits and the local economy. Some parts of the country are just expensive no matter what you do and for the same thing with the same results, you can pay twice to four times as much. Recently, it's becoming harder to get a permit for a regular septic system. Arobic systems are the prefered method in some of my local counties, and they are in the $8,000 range to have one installed for a 3 bedroom home.
I know a guy who spent $100,000 for a system to handle a 24 space RV Park near here. He wasn't happy about that, but didn't have a choice.
If you fill out your profile, more specific details for your area can be shared, if not, then these figures are good starting numbers for East Texas.

for a 3/4 mile of phone line(1/2 mile on my property and I had to pay for a 1/4 mile on public right of way). I decided I could get along fine on cell phones
