The assembly of my prototypes was handled very well by PCB Way. I use them regularly to complete my small batch orders. However, this time I used the Kicad plugin to make a virtually one click order. Getting this set up was important, especially as I wanted assembly - without the TH components - only SMD. Now I have Kicad configured with the correct BOM fields and options I am happy to use it again. You still get the ability to approve the price and details once you submit the order. As always the team at PCB way are quick to communicate any layout issues or placement orientations where this is important to get visually correct.
