Well looks like I am maybe a "NO SMT ASSEMBLY" unless a green star is ok.
NOTE: smt assembly ONLY on green boards. Asked JLCPCB
Geez oh grief. How can the fact the JLC's assembly service will make only green boards be unknown to you?????
Once again, you have made me truly regret wasting my time trying to help.
At the risk of opening a very large can of worms, you could have boards assembled by JLCPCB. My only relationship with JLC is that I'm a satisfied customer.
Let's assume your board is 100mm × 100mm or less. The cost for board assembly breaks down like this:
1. Cost for 10 boards, engineering services and stencil: $13.50
2. Cost of components (per board): ~$3
JLC only has the PIC18F46K22-I/PT in stock. It's the big brother of the 18F43K22, with much more memory. It's $1.95 for 10+ pieces. The resistors, caps and LEDs would be pennies each at most. Probably less that a buck a board.
3. Cost for "extended" parts: $3 total.
The PIC is an extended part, meaning there's a charge to set up a pick&place machine with it. With careful selection, all of the other components should be available on the "basic" list.
4. Cost per pin for soldering: $?
This is some insignificant amount that I never even notice on my builds.
5. Shipping – DHL: $17
So for roughly $65, you'll receive 10 boards with [only] the surface mount parts installed.
Read this carefully: soldermask option is green. SMT parts are soldered to one side of the board only, and through-hole parts are your responsibility. Only parts in-stock and in their SMT library will be installed, and parts not on the basic list incur a $3 setup charge, which should only be for the PIC if other parts are selected carefully. Parts not in stock or not in their library won't be installed.
You're paying essentially $8.50 to have a lot of 10 boards assembled and getting a break on component costs buying though them.
If you want to do this, I'd recommend using JLC's free EasyEDA software – it will make it easier to provide BOM and pick&place files in the proper format. It's easy to use with a simple learning curve.
I have used this service for several boards and have been extremely pleased with the results. But be absolutely clear on one thing: For a successful build, it's entirely up to you to select components from their library and in-stock, and to be aware that only surface mount parts are part of the service.
