Installation electricity

Hei, We would like to ask for a quote regarding the installation of electricity. Specifically, we would like to have installed: - a new electricity group in the electricity box (which is placed in the hall on the upstairs floor) - From this new electricity group, there should be going an electricity cable to the attic, where we have built two new bedrooms. (It’s a small hall and small stairs, so the cable will not have to be long) - Each of these two new bedrooms, should get one new wall outlet (stikkontakt) - From the new electricity group, there should also go one cable to one of the already existing bedrooms on the first floor (really close to where the electricity box is), where we would also like to install a new wall outlet. - In this already existing bedroom, there should also be installed a second wall outlet (from a cable of one of the already existing electricity groups) Could you provide an overview of what this would cost? We live in Singsås. Thank you in advance! Best regards, Jolene van der Kaap-Deeder
