I've replied about this below to Jan.

I've linked my post about the number of staff the Dashwood ladies might have and what they could be expected to do,here, whihc mihgt help you. Bascially they had probably a cook, a general maid( who would probly do the laundry too) and a man to do the heavy work.

I do think Fanny Dashwood would be stupid to attempt to dismiss her staff wholesale, however tempted she might be: staff were notoriously difficult to get in the country. London staff were reluctant to move to the country due to the difficulty they would have getting a new situation iof their present one in an isloated rural area proved uncomfortable/unsiutable: they preferred to stay in town where jobs were plentiful, and they ahd some choice and also some chance of entertianment during their time off.

The "servant problem", that is getting them and keeping them, was present throughout the 18th century( see The Gentleman's Daughter by Amanda Vickery for tales of runaway servants et al).
