| Price | Fixed project quotes; small firms from about $2,000 per build, large agency retainers $10,000 to $30,000 or more a month | Upwork lists AI engineers at a typical $35 to $60 an hour, and AI API integration projects at about $1,000 to $4,000 | Freelancers usually cost less per hour. Compare the total for the finished, tested job, not the rate. |
|---|
| Scope and quote | A written scope with a fixed price before work starts | Often hourly, sometimes fixed; the scope is as clear as you make it | Whoever you hire, get the scope in writing with what done looks like. |
|---|
| Accountability | A business with a reputation, terms and usually a warranty period | Marketplace reviews and escrow; quality varies widely between people | Check past work and references either way. A warranty in writing is worth more than a review score. |
|---|
| Availability | Cover when one person is away, but you may not work with the same person each time | One person, often in another time zone, who may move on to other clients | Ask who will support the system in six months, and get it in writing. |
|---|
| Support after launch | Care plans or managed plans with a set response time | Ad hoc, at the freelancer's next opening | For anything customer-facing, agree support terms before the build starts. |
|---|
| Documentation and handover | Usually part of the deliverable | Depends on the person; ask for it in the scope | Without documentation, you depend on whoever built it. Make handover a paid line item. |
