one last clue
20a sounds like a really small place of business?(4)?e?l ( is it cell?

[bookbinder]

I prefer sell. The clue says 'sounds like a really small place'. A really small place could, indeed, be a cell, but the answer cannot be cell because the answer has to sound like cell. 'Of business' confirms that sell (which is what you do in business, I suppose) is the answer.

I suppose 'Mill' is out of the question if your letters are correct?
