I'm looking for about 1km of thin-ish solid copper wire, as cheap as
possible.

1. Solid, not stranded
2. To be used as single wires, in lengths of typically 10m
3. Could be insulated or bare, tinned or not; but not enamelled (unless
the price was very, very right)
4. Strong enough to cope with being laid on the ground outdoors, and
then generally trodden on and mowed over
5. Thin enough to be cheap.

About 1.0-1.5mm diameter would probably be fine.

In the catalogues, the best options so far seem to be multi-core cables
of some kind. 12-core telephone cable is a reasonable price from TLC,
though it's thinner than I'd prefer, and I'd rather not to have to strip
and untwist it to get to the individual wires.

Solid twin bell wire from TLC would be fine, but significantly dearer
per 100m of single wire. (Screwfix bell wire is stranded, so no use for
this.)

Any better ideas from you intrepid bargain hunters, please?
