Do you not have any tools? Are you a real man?!?!?!
On a serious note, I used to be very wary of doing jobs myself. Always thought I'd mess them up, always thought I'd do a much worse job than a 'professional'. Then I paid a few said professionals and realised that I could often do the job just as well, often better in fact as I was more careful of my own stuff! Don't get me wrong, I won't touch gas at all and I'm wary with water as a screw up can be very costly, but electricity is fine and general drilling/cutting/fixing is becoming increasingly easier. I even re-soldered my OHs boiler last year as a new PCB was rather expensive and the broken component was only worth a few quid.
The main thing you need to know is how deep the cavity is behind the plasterboard, as it is an external wall it could be virtually none existent or could be 8cm+. Usually you mark up where you want the screws to go then get a very small drill bit and put in a pilot hole til it stops (hits the brick), you then pull the drill back out and measure how much went into the wall. Whatever that size, you need smaller fixings.
The fixings have 2 measurements, the diameter of the hole (or is it the screw?) and the length of the fixing. The first measurement will be M4 or M5 usually, the higher the number the wider the screw. Its best to check the screws that come with the curtain pole, and go for the same size. If you go too wide the screw wont go through the pole fixing, I've made that mistake before! The second measurement is its length, you need shorter than the depth measured on the drill bit but ideally only just shorter.
Although you can use the fischer bits without a setting tool I REALLY recommend getting one, its too easy to screw up the plasterboard otherwise. Can't see a fischer one, but screwfix have the
rawlplug one. This holds the fixing tight and expands the arms behind the plasterboard, holding it in place. You just drill the hole, put in the fixing then pull the arms of the fixing tool together to bend it into shape. Then you need the fixings themselves, I'd probably expect the
M4x40 to work but you'd be better of checking the wall/curtain poles to be sure. Those 2 together makes £18, and you get 20 fixings. If you can borrow a drill its a cheap job to do yourself.
Hope thats of use, unfortunately I have the little 'un on Saturday otherwise I'd have come and given it a go for you.
