Hi dont do it, go for office and commercial, reason is you will have signed contracts and will be worth somthing, and if you want a morgage the bank will not lough at you like they would if you told them you have 20 domestic cleaning contracts with no contracts who can get rid of you any min!
Also if you ever wanted to sell you would be worth more.
But up to you, if you do domestic plan it right and hit local free mags advertise for £30 per month
But if you have money i have 2 franchise pacages

lol
