Like I said, the only way to conventionally burn this with a straight sink is to angle the barrel, the 5 degrees is just a guess. But trust me I know how it goes, you might go to 10 different shops that have the capability, but will turn it down because they're too lazy to try to figure it out. Show up with your end product and say "I want these made" and you're likely to get a dumb look. But show up with drawings of the electrode profile, tell them what angle to burn, with rotary indexer, etc. and you're much more likely to get them to take the job
I'd help you but my shop does not have an EDM yet (actually going to acquire a Charmilles likely before the end of the year) I have friends at the shop I used to work, ...carbide work, lots of EDMs, but they're more contractors for Kennametal than they are a job shop so they would not be able to help, meeting Kennametal deadlines is top priority and I never saw them take in a job that wasn't Kennametal or a subsidiary.
Best of luck
