Any sailmaker will be able to put in reefing points, but few will know where to put them.
My recommendation is 2 sets at 1m and 2 m above the foot of the sail.
Assuming you have a jib in your wardrobe – and you must have a jib or a proper headsail reefing system – set jib plus 1 reef at F4/5, jib + 2nd reef at F5/6.
Oh yes, and don’t ever beat with a genoa and a reefed main – that’s asking for trouble.
