Startup cost: $500 - $3k

Startup costs for an AI Code Review and Optimization Service can range from $500 to $3,000 depending on your approach. At the minimum end, you'll need to cover basic expenses such as setting up a website, marketing materials, and possibly some initial software tools. Opting for the higher end would involve investing in premium website design, advanced AI optimization software, and professional marketing services. Essential expenses include website hosting, domain registration, software subscriptions, and initial advertising budget. Optional costs might include hiring a graphic designer for branding or investing in advanced AI algorithms. Hidden fees to watch out for could be monthly software subscriptions or unexpected marketing expenses. Online feedback suggests that while starting costs can be relatively low, they may increase once you commit to premium tools or services. To take this side hustle seriously, I would recommend budgeting between $500 and $3,000 to have a solid foundation for your AI code review business.
