There should be a tipe of screws and size. Of course you get them on faster with an electric drill.
I'm not aware of anyone hanging brackets, unless you purchase custom window treatments. In hardware, the workers are versed enough to advise you on the correct screws to use for your type of walls. It's simple with a screwdriver, an electric screwdriver is faster and easier. Home Depot rents tools. Check to see if screwdrivers are available.
I'm pretty sure you do that on your own
