There is not very big search for such type of services. You should try to attract attention with some promotion.
You can promote it all you like the vast majority of people won't pay the prices that relates to the time required to do the work. Even if they do the hourly rate is still sub carpet cleaning rates, infact it can be well sub window cleaning rates.
Today I finished a 2 day job to recolour a 3-2-1 suite from cream to tan, that was 12 hours work in total. Cost of products to do the job.... not far off £100. Total cost to the customer £600 but take off £100 for the Vat element.
This was a good day at well short of £40/hour whereas I aim for a fair bit more on the carpet cleaning side.
The handbags I've mentioned can take 2 hours and you'll be lucky to get £60 for it, yes there are exceptions but not many.
