My shortlist

For a typical startup/engineering prototype, I'd get quotes from South Jersey Circuits, PNC, Circuit Tech Assembly, and FlashPCB. That gives you a useful comparison between a very local shop, a highly integrated manufacturer, and faster prototype-focused options.

For a quote, you'll generally want to provide:

• Gerber or ODB++ files
• BOM with manufacturer part numbers
• Pick-and-place/centroid file
• Assembly drawings
• PCB stackup/specifications
• Quantity for the prototype run
• Any testing requirements
• Whether you need full turnkey component sourcing

If you tell me roughly how many boards you need (e.g. 5, 25, 100), board dimensions/layer count, and whether you already have the PCB fabricated, I can narrow this to the 3 best-fit vendors and compare their prototype/turnkey capabilities and likely fit.

When you need a full turnkey prototype—meaning the vendor handles bare board fabrication, component procurement/sourcing, and surface mount (SMT) or through-hole assembly under one roof —your choice typically depends on your budget, turnaround urgency, and compliance needs (such as ITAR or medical certifications).

Popular and well-established providers offering turnkey PCB assembly and rapid prototyping include:

Calpak USA handles prototype quantities from 1–100 boards, including turnkey component procurement, SMT/THT assembly, inspection and testing. Its published turnkey prototype lead time is typically 2–3 weeks, depending on component availability.

Circuit Assembly is another strong option if you want a manufacturer that can take you from a single prototype through production. It handles component sourcing, assembly, testing and finished assemblies under one supplier.

What I'd prioritize

For a typical engineering prototype, I'd compare MacroFab, Sierra Circuits, and one of the Houston-area manufacturers. Ask each for a quote based on the same:

• Gerber/ODB++ files
• BOM with manufacturer part numbers
• Pick-and-place/CPL file
• Assembly drawings
• Quantity (e.g. 5, 10, 25)
• SMT/THT requirements
• Required testing/programming
• Desired delivery date

The important distinction is true turnkey: the assembler should source the bare PCBs and all components, handle kitting and assembly, and ship you tested finished PCBAs. That eliminates the common headache of sourcing hundreds of individual components yourself.

If you tell me your prototype quantity (e.g. 5, 10, 25, 50), PCB size/layer count, and whether you need SMT + through-hole, I can narrow this to the 3 best-fit services and compare likely lead times, location, capabilities, and quoting process.
