This type of project is best left to an electrical contractor. The pole has to be permitted and inspected. When the electrical inspector is satisfied that the installation is safe he will submit his connection form to the utility company for a connection to their lines.
The type of conduit system is governed by two factors. One the code book states what type of system can be places in what specific locations. The second factor is what the electrical engineer specifies that what he wants the conduit system to be on his project. EMT is used in the majority of jobs for industrial and commercial projects. As a conduit system it is easy to install and more circuits can be added to the system very easily abiding by the code book rules for conduit fill.

Not always, the electrical code is quite specific as to the type of installation where the ground wire needs to be insulated and in what type of installation the ground wire can use bare copper.
Price depends on type of work, time of year and location.

it is a type of installation that is concealed. So that it calls concealed type installation.
The current-carrying capacity of a cable depends on a number of things in addition to its cross-sectional area; these include the type of conductor, number of cores, type of insulation, whether or not it is armoured, method of installation, etc. Accordingly, to determine its current-carrying capacity, you will need to refer to your national electrical code. For example, in the UK, BS 7671:2008 Requirements for Electrical Installations contains tables for all standard cable types, specifying current-carrying capacity, voltage drops, etc.
You don't calculate the current-carrying capacity, you find out from the appropriate Tables in your country's wiring regulations. In the UK, this is BS 7671:2008 Requirements for Electrical Installation.The reason you must do this is that the current-carrying capacity of a cable depends on the conductor type, number of cores, the type of insulation, the method of installation, etc. Allthese factors are taken into account in these Tables.For a 2.5-mm2 copper cable, the current-carrying capacity can vary from around 22 A to around 36 A, depending on the factors described above.
