I got quoted around 3k for car repair. Any mechanic recommendations for second opinion?

There is a rattling noise when I start the car and the mechanic I usually go to quoted me $2800 on 2012 Camry with 175K miles. He said the issue is with timing chain which requires significant labor. $900 parts and $1900 labor. I was wondering if you guys have any recommendations for a mechanic in West side of Houston for a second opinion ?
