Your Hunter is a well-recognized class of boat. I would expect that most sail makers have access to the generic size of sail. That being said, you will get a generic-designed sail. This may meet all of your needs, and the price may be affordable.
For not much more money, a local sail loft can bring value to your experience. I chose North Sail in my area. I have a knowledgeable professional come out to the boat and measure the rig. This meant that when the sails are fitted, the draft will be in the optimal location. The sail slugs will fit the track on my mast. The sailcloth on the genoa will provide a chafe guard at the height of my radar and the spreaders.
These may be little things, but they all help to maintain my sails in optimal condition. If, when hoisted, the sails had not fit properly, they would have been taken back to the loft for adjustment. Poor fit happens.
If something happens and you need a repair, you have a local resource to access.
There are boat owners who order sails by mail. Good luck.
