Looking for sewing help for my upcoming pillow collection

Information for the business: illustration/textile company
Industry: Art and Design
Design details: The job is pretty easy as I just need some help to sew throw pillow covers with a simple zipper in one of the seams, sewn with my fabrics. Two sizes 65x65cm and 50x50cm. My textile printshop where I'll be printing my custom fabrics for these pillows is located in England, so to save on shipping I'd also like you to be located in England/ UK. I myself am located in Stockholm, Sweden.

For the moment I'm not quite sure how many pillows I'll be creating. But most likely between 50 and 100 total. I'm looking for someone to sew these for around 4£ each £200 for 50 or £400 for 100.
The fabrics are simple cotton, and a cotton/linen mix. I would also need help supplying a simple white zipper.

My deadline is kind of open. I would just like them finished in February or March at the latest.
Target audience: seamstress
Ideas for the visual style: pillow covers in two sizes
