you people must shop at another store from me...
looks like an old pile of scrap that someone threw together... a grand? not ****in likely! you can keep your shop...
I wouldn't personally pay $1000 (although I've added one to my list of DIY projects, might get to it in 3-5yrs) but there those that would, I had a client who paid almost 20 times that for a feature tree now the new owners have flagged the idea of cutting it out but can't yet bring myself to do it. The majority of my clients wouldn't even blink at $2500 for one if they wanted one. The issue for Fergy is that while not everyone wants one, some would and getting visibility to those who would is easier said than done.
ideally would like to sell them to fund some toys
I would get some reasonable photo's (don't need to be professional but not full of stuff in the background) of the three you have, get a very quick intro down pat, set aside a few hours and call as many landscape architects or larger architect firms that would have a landscape architect as you can to see if you can email them through some pictures. Something like
"Hi I'm John from Johns fabrication, we have just started producing some bespoke sculptural/focal piece fire pits and were wondering if I could send you through just a one-off email with some examples of what we have already done.
Whilst I think the concept of the first one you posted is good, the execution isn't quite 100%, probably needs to be a bit more homogeneous with the layout of the scrap so for that one I'd make sure to get it from it's best side, or maybe take a pic of it with a fire in it.
