Plastic enclosure for small product

I have a small hw product and I would like to find a plastic enclosure company that do small runs.

Recommendations with experience please (i.e. not a simple Google Search result dump!)

Answer

I would say that to keep costs to a minimum you need to try to fit your product to one of the standard enclosure boxes made by (for example) OKW. The problem with a bespoke mould for your product you are looking at a large NRE charge for the design and some thousands of pounds for the tooling costs.
