Clearly scoped thermal analysis work with fixed price, stated deliverables, named software and standards, and an explicit list of what is not included.
What is the difference between a service and a project here?
A service is predefined scope with a stated price, deliverable list and delivery date — you buy it. A project is custom scope where you describe the problem and qualified engineers propose a methodology, milestone plan and price. Anything genuinely bounded suits a service; anything uncertain suits a project.
Is what is excluded actually listed?
Yes, on every listing, deliberately. For technical work the exclusions matter as much as the inclusions — professional sign-off, statutory submission, site supervision and native source files are the ones people most often assume are included when they are not.
What if I need it faster?
Most listings offer a priority delivery add-on that halves the timeline for a stated fee. If your deadline is immovable, say so in the first message rather than after ordering.
