Satellites
Here is a good website that may answer many questions on freesat.
This website is free to join.
I worked in Saudi Arabia and Turkey for a quite a few years, lots of free programing there with the Nilesat, Hotbird and Albadr Satellites.
Some of these Satellite foot prints will cover Europe as well.
Used this site quite a bit over the years, lots of good info there.
From Dish size, Installation, to programing.
You can do all this yourself, not all that difficult and save quite a bit of money.
If you are scared of heights hire the pro for the installation, saving a bit of money is not worth getting hurt.
As long as you have a clear view of the sky in the proper direction and elevation without buildings or trees blocking the signal you can get quite a bit of free programing.
Dual or triple LNB's should be available from satellite dealers.
Once the dish is aligned properly changing/upgrading the LNB to a double or triple or even quad is a easy task, just 2 screws new LNB and the added coax cable for the additional receivers.
Enjoy.
