How do you say gaines?

Excuse me, I'm a bit confused about the pronunciation of the word "gaines." Could you please clarify how one would say it correctly? Is it pronounced with a hard "g" sound at the beginning, similar to "game," or with a softer sound, perhaps closer to "jine"? And regarding the vowel sounds, does the emphasis fall on the first syllable, making it more like "gain-es," or does it shift to the second syllable, sounding more like "gai-nes"? I'd really appreciate it if you could demonstrate the proper pronunciation for me. Thank you in advance for your help.
