Look first at proven experience, laravel development outsourcing not the size of the portfolio. Request three or four engagements that match your stack, and then find out who actually wrote that code. A solid partner is happy to connect you with the engineers. Vague answers at this stage almost always mean the demo work came from somewhere else.
The contract needs a slower read than the pitch. Three sections matter more than the rest: assignment of intellectual property, confidentiality, and exit terms and handover. All the work product has to transfer to you once invoices are settled, including documentation, pipelines and deployment scripts. Watch for any clause that leaves so-called reusable libraries outside the transfer, as it is usually the part you cannot replace later.
Ask where their numbers come from. A credible estimate is accompanied by a written set of assumptions, a task-level breakdown and an explicit range. A fixed-bid deal works only when the scope is genuinely frozen; in any other case the provider adds a risk premium and you fund the buffer regardless. Time and materials shifts that risk to you, so it demands a cap, what is livewire in laravel regular demos and transparent reporting.
The delivery process matters as much as headcount. Ask what happens when the scope changes, who writes the acceptance criteria and how much does it cost to build an app quality assurance works. A team will be able to walk you through running nearshore software development rather than status reports. Acceptance criteria in writing remain your only real protection against endless rounds of rework.
Last, plan for the day you no longer need this vendor before it becomes urgent. Ask that the code repository stays on infrastructure you own from the first commit, and that a readme and architecture notes are kept current as the code changes. A vendor with nothing to hide will agree quickly; a long negotiation over it tells you quite a lot.
