You could type the words wanted and find a font that suits, it would be easy to then use lightburn and get cut with a fibre laser using the font as a template and then using it as an outline, type it up and size it correctly including the width, then print as a PDF as its easier to import. Probably best if the metal/stainless is only a mm or 2 thick. alternately you could do the same using a CO2 laser and using acrylic with a 'metalised' cover, although this will allow the black acrylic to show at the sides.
The metalised acrylics are relatively cheap and it would cost a few minutes of cutting plus materials. First thing is to choose the script, but you could get the outline done a for a few pounds using fiverr as its that artwork that would cost the most to get done professionally in house with the cutter most likely.
