London. I tried a local lady's service once, from the newsagents window, it was such a hassle what with getting it ready, organising hangers, pickup and collection appointments (whether I dropped it myself or not), it took about 10 phone calls and she charged a fortune and took 4 days to get it done.
Mostly I now have a cleaner do it "in house", it's a handy "extra" that they can do to fill up the time paid for if the rest of the house is fairly tidy to begin with. Also now I can pop out to corner shop while dds watch tv if she is there ironing, they won't go with me without a fight. Might miss Numberjacks.
It takes her about an hour to do 7-8 man's shirts and she get's about £8 and hour after tax.
Another service I've seen charges £1 an item, a man's shirt or single sheet being one item, minimum £19, they provide the bag, pickup and delivery, 2 day turnaround. they wallpapered the neighbourhood with leaflets.
I would love a dedicated ironer who came to my house. Even better if she came with her own equipment, the cleaners wreck mine or leave it lying around. Would you consider that and even to bring your own iron? (I don't mean for me, just in general).
