I got ICP, NCMA membership for a year free, first aid free from LA.
I had to have my internal doors changed (they were glass) shelving installed, display boards put up, part of the garden fenced off and a couple of other buildery bits. This cost approx 1 1/2K.
I then had to get flooring, tables, chairs, high chairs x2, safety gates x4, fire extinguishers x2, storage boxes / units / free standing shelving, travel cots x2 and all the associated bedding, flannells loads, nappy bin, changing mats, various car seats (have 9 at last count as well as booster seats)lockable steel filing cabinet, mounds of stationery, advertising costs the list goes on and on.
Also ordered a years worth of paint, glue, brushes, paper, craft stuff, display board backing paper etc the cost of that alone was £600.
All in all my initial set up cost was approx £4K. But I knew when I started what I wanted to present as and quite frankly my place does look like a nursery, I filled up within a few weeks and needed an assistant. This job is now my and DH main income, we rely on it now so although we do spend a large amount compared to a lot of minders it is proportionate for turnover IYSWIM.
Most CM's have a fantastic business with minimal outlay, I think what I did at the start was extreme for a minder but I wanted to provide something different and it has worked for me.
