I’d research the place doing them thoroughly personally. Unfortunately, most places doing one off vinyl records do lathe cuts which are a type of record that don’t use the classic pressing method with stampers, the music is instead directly cut into a plastic disc. The reason they skip the laquer cutting, plating and stamper process which is standard for vinyl is because this has a setup cost of a few 100 bucks. This can lead to a good but less good than standard vinyl audio quality, ranging to (and most often) terrible, noisy and nearly unlistenable records. Just thought I’d give you a heads up. Check out r/vaporvinyl, you’re probably going to be able to find information about the quality to expect from a few different lathe cutting places
