not sure how you would go about doing the lower portion of the front of your car but the grille is simple to make your self for cheap* too.
buy some wires mesh like this from anywhere near you, that looks like diamond cut mesh- measure and cut the acquired mesh to the inner portion of your factory grille.
then paint it black or what ever color you choose. remove your stock grille and remove the insert behind it (the black insert) and then take your painted new mesh and snap fit it in to the original insert clips.

as for the bottom, it will be more work. ive seen it done before, so its possible.
i did this on my 88 jeep cherokee XJ. fairly the same "how to do it" since the grille are virtually the same just different shape. later down the line i added the billet look on the outer portion of the grilles housing.
