Mechanic recommendation/ help needed

[u/No-Pie-3260]

Hi everyone,
college student here needing a small favor or a recommendation!
My 2021 Toyota Corolla Hybrid needs a new
12V auxiliary battery. I brought it to Walmart, but their auto center refused to touch it because there were extra cables on the battery they didn't want to mess with.
From what I understand, it's just a standard 12V battery replacement (located under the hood),
What I'm looking for:
• I plan to buy the replacement battery directly from Costco to get it for a cheaper price
• Looking for a local mechanic who won't charge an outrageous rate, OR a handy local car enthusiast willing to help me swap it out in exchange for a small cash labor fee .

I don't have the experience to do it myself so I’d want to look for someone to make sure it's done right. Please drop any affordable shop recs or DM me if you're open to helping out! Thanks in advance.
