SW London based Seamstress to sew cushion covers

I am starting a small business and am launching a collection of linen cushions. I have been working with a lovely East London-based seamstress to make up the prototypes and samples, but she lives too far away for ongoing work. I need someone within easy striking distance of Wandsworth.
Can you whip up a beautifully finished cushion with overlocking on edges, label sewn in and a concealed zip finish?
The company launches mid-January so it is hard to predict how many I will need sewing - 10? 30? 100?
I can pay £6 per cushion cover.
It would be doubly brilliant if you were able to drive in order to pick up/drop off orders from me (Wandsworth) but this isn't essential.
