I make and fit gates to order.
Here are a few of the gates that I have made.

It is very important to give your new gate a good couple of coats of oil based paint or stain to protect it and to stop it from swelling.
Wood is a natural product and if exposed to the elements, it will expand and shrink if not protected. If you are unable to do this, then I am happy to include painting or staining in your quotation.
