This is a HAM service which in general did not generate, but COSTED me money ! It was an important part of my hobby and kept me busy serving you. In schematics i sometimes do NOT give component values.
But component lists will always perfectly coincide with PCB layouts.
Placing components will be without problems.
Why ? Some of my designs were copied without my permission, and sold cheaply using inferiour or wrong components. But byers were directed to my site or my email address for all building info ! No thanks. 

20231011 :
I do not sell completed PCBs. Reason : my weak health, and keeping components in stock is to costly.
 WARNING : i now only sell what i still have in stock.
 Once a PCB is soldout, NO new PCBs will become available.
Why ? I do not bussiness anymore with Chinese factories.
Other factories do not make small PCBS or in low quantities, OR they are very (VERY) expensive.
HOW to order PCBs.
