Perhaps you might consider a self-publishing print-on-demand
arrangement for your handbook.  Kindle Direct Publishing, formerly
Create Space, is owned by Google.  I've produced two books of my
newspaper columns through them, and while it's a tedious process
because you have to do all the work yourself, it avoids the financial
outlay of purchasing an entire print run because each volume is
produced with a some sort of mysterious automatic book-making
machine that prints, cuts, and binds it into a paperback book with
a shiny (or matte) cover.

My first silly book ("The Hanging Gardens of East Mulberry Street,
and other tales of domestic valor") will shortly be joined by
"And Now a Word from Mr Excitement and other stories" on Amazon.
I priced the books (arbitrarily) at $9.95 and the printing cost for
each one is $3.25 or so.  This makes a profit for Amazon and for me,
and for the newspaper that actually owns my columns.  The books are
about 200 pages or so, 6"x9", and seem like perfectly ordinary books.

Pictures, color or otherwise, can be included in the books, though
I have no idea how much these cost.  Most important for me (and the
newspaper) is that there are essentially no up-front costs.  Your
customers can purchase books at your list price from Amazon (and
you can also publish editions for the Kindle book reader) and you
yourself can buy copies of your book wholesale -- one book or many,
at the printing cost plus shipping.
