My advice is to leave that particular set of pipes well alone. They are made in Pakistan, are of shoddy quality and are rarely tuned correctly. They are the equivalent of a BSO. If something goes wrong with them or they don't work you will have difficulty finding any pipemaker willing to attempt to repair/tune/retune them
A typical quality chanter costs £750, a cane reed £50 the airbag around £100 and the bellows £200 if bought individually. A quality wooden practice set can be had for around £1000, a delrin practice set costs around £400.
If you are determined to acquire a set of pipes spend some time on the Chiff and Fipple web site
http://www.chiffandfipple.com/. Although its primary function is to serve the tin whistle community, there's lots of information and advice to be had there for uilleann pipers.
If you want proper pipes look at
Ray Sloane's site
http://www.raysloan.com/ 1,500 euros for a practice set
Brian Howard
http://www.howardmusic.co.uk/welcome.htm around £1,000 for a practice set though his web site hasn't been updated for several years
Second hand quality pipes can be had here

If your ambition is to play Irish music a much cheaper alternative to uilleane pipes is a low whistle - a bigger version of the tin whistle
Have a look at the range on offer here:

You should go for the ones tuned to the key of D to be able to access most of the Irish tunes without having to transpose the fingering charts to suit a whistle in other keys.
