When you say chandelier, do you mean a chandelier style shade, such as this one...
or an actual chandelier like this one...
If you want the shade, and you have already have a pendant lamp hanging from the ceiling, you could easily make it by attaching strings of glass/plastic beads to a metal hoop/lampshade base and fixing it the ceiling pendant as you would a normal lampshade. You could probably use a bike wheel or something with a similar shape as the metal hoop, with a hole in the middle to go over the light fitting and a hoop on the outside to hang the beads from.
If you mean the actual chandelier...try the usual haunts - Ebay, thrift stores, salvage yards etc. If there happens to be a bar/restaurant being re-fitted in your area, maybe they have old chandelier fittings which they are getting rid of and would give you. You could get a cheap 3 or 4 light fixture and jazz it up a bit with plastic/glass bead strings draped around the arms and get some of those bulbs that look like candles. If you did get a light fixture that did not work, you could try hanging it from the ceiling (making ABSOLUTELY CERTAIN there is no way it can be wired in) and put candles in the light sockets.
As Junk Peddler said though, if you have limited experience in wiring and electronics, re-wiring a chandelier is not a good place to start practising.
A mural, eh? That would look great in a Parisian room - as though you were sitting at a little cafe and looking out on the river or whatever
Try the Rasterbator
. If you are artistic, you could make an abstract mural using fabric...find a picture and 'copy' it onto the wall using fabric in the basic colours and shapes used in the picture...turns out kinda like a Monet picture I suppose - (More info here
on how to use starch to attach the fabric if you need a non-permanent solution)
This would also work with a selecton of recycled materials e.g. using leaves to create the green tree leaves etc.
It would also be cool to create a Geometric String Eiffel Tower
