I had the same dilema 6 years ago when starting 365Drills. Wanted something memorable but then after weeks of debating settled on something really simple.
There are names out there that have been totally made up like Rolex that have no real meaning. Or you can do what a lot of people do and go down the PUN route.
A lot of people like the play on words things. For my sector we dont use puns. More serious is better. if you look to the right at all the sponsors most of them have serious names but its 50/50 as to if its product related. Like Mapei means nothing unless you are in the industry.
I would go along the lines of:
Quality Tiling and Plastering Ltd (QTP Ltd)
Tile & Plaster Co
Plaster and
Tile Group (PTG)
If you want puns then maybe
Tile-Her
and of course
Plast-Her
Or Plast and
Tile Her
or Plast her and tiler Her (PHTH Ltd)
But do lot of research. I branded the name Porsadrill 5 years ago for our
tile drill system but to begin with I split
the word Porcelain and Drillls to make _PORC-A-DRILL
But then people started to call it PORK a drill. Arggggghhhh.
Back to the drawing board and when the phonic route. PORSA
Good luck I know its hard so take your time !!
