Sewing Service Wanted

Looking for someone to make a custom chair cushion for my antique wicker/rattan chair.
47 x 22 with square edges.
Soft, comfortable, and stylish.
Thinking of a natural, light linen.
Please see pics of the chair.
There is also a pic of the worn out cushion I presently have.
There is also a pic of a cushion I like, but would like square corners to go with the shape of the chair.
