Most Loox work is small, well-defined, and priced per project. You rarely need a retainer — you need someone to do a specific thing properly once.
Name the outcome, not the app. "Set up Loox" gets you a widget on a page. "Get photo reviews above 40% of total submissions and match the widget to our theme's typography and spacing" gets you comparable quotes and a result you can check.
Match the specialist to the job. Theme integration and widget styling is front-end work — Liquid and CSS, usually $300-$1,200. Migration from another review platform is data work, $500-$3,000 depending on review volume and whether photos are coming across. Review-request flow strategy sits closer to email marketing than app configuration, $500-$2,500. Schema and rich-snippet fixes are technical SEO, $400-$1,500.
For migrations, ask about photos specifically. Review text usually transfers cleanly. Photos and videos are where migrations quietly fail — they may not carry across at all depending on the source platform, and merchants often discover this after the old platform has been cancelled. Ask directly how the specialist handles image transfer, and keep the old platform active until you've verified.
Ask to see a live store they've styled. Loox widget integration is visual work. Two minutes on a store they've configured tells you more than any case study — look at whether the widget reads as part of the theme or as an app bolted onto it.
