layout question

Can anybody help me with this?
I lay out my schematics by myself. It was done by outside contractror
once - I had to redo it: few switchers on fairly densely populated
board, one needs to look at the schematic (and understand it) while
doing layout...
Question 1.
how do other EEs do it? Sensitive mix of analog and switching stuff...

I need to lay out another PCB and first thing I have to do is to create
footprints that are not in our library (some QFN packages, few
connectors)...
Question 2.
Has anybody heard of the service/source where we can order the
footprint from? Something that works like this: we send datasheets,
and/or footprints names, give CC number and get either library of 1,
2...10-20 parts..
I do not want to buy library of 10,000 parts and spend hours trying to
find my footprint there.
And it would be nice if I could use the footprints WITHOUT having to
check them (like Samtec QSH footprint I dealt with the other day)
Am I daydreaming?
Thank you for your help!
