You might want to give it a try.  With the exception of BGA, which is
for specialists only, SMT parts can be handled perfectly well in the
workshop with nothing more than a good soldering iron, thin solder, a
bright light, and a magnifying glass.

You might want to look for some back issues of QST (or perhaps QEX);
there have been some good articles about SMT for amateurs in there.
Included were examples of people who made boards for SOIC parts with a
Dremel tool, or an Xacto knife.  I personally prefer a CAD program and
a board shop, but for small pin counts I'll admit the other is
workable.  Yes, if you want to use 240 lead PLCC parts, you'd better
farm out the PCB fabrication to a good board shop, but all the rest
you can do yourself.

It's hard to imagine a PCB shop that can't make boards for those
applications...
