See if you have any laser etching firms local to you.

It would be much easier to get the metal cut to the outline shape, painted and laser-etched than to cut and weld a silhouette. The ones I've done of dogs before would have been a nightmare to get any detail if I were cutting instead of engraving.

electroplated then not galvanised as the galvanising will hide the detail

I get you mate, I was thinking the same with powder coating

We used to use hot zinc spray on mild steel, then paint it. The paint adheres well and it lasts for a good few years.

Mill finish stainless wouldn't need this, of course, and would last forever.

Taking enfieldspares design and chain drilling and filing it would not actually take that long, so ignore my original jokey post.

what about enamelling.........get a photographic enamel transfer made and then have the whole thing enammelled baked ?

you often see examples of this in the potterery industry

Ah! Vitreous enamel. A specialist skill, not sure if there are many around in the UK, though. Works well for straight edged signs as long as the edges are protected, but the ears on this shape would be prone to chipping. Expensive for a one off.

If it was just a laser cut plate you were after in the shape of the profile you could soon insert the image into autocad and then draw around the bits you wanted. Save the image as a DXF file...off to the laser cutters and job done....simples. You could then add as much detail as you wanted (within reason) ensuring you had continuity in the plate you were cutting. You don’t want to cut big bits out that made it fall to bits (if that makes sense)

however you do it....sandblast it and get it anodized...then have it sprayed up......

If mild steel zinc plated ! Not galv will be full of crud and likely bent with distortion.   Anodising is what you do to aluminium alloys not steel as a house sight would normally become in 

Personally speaking I like copper for this kind of work especially well aged in the weather
