Here's a part of a book below, and I can't get the meaning of “ little lot. ”

Could you explain what this phrase means and what part of speech it is?

I can't tell it means either “ a little of money ” or “ a lot of money.”

Jackson shrugged. “ OK, ” he said reluctantly, “ but I expect service for this little lot, old buddy, and if I don't get it...” “ Trust, Joe, another of this world's more saleable commodities. ” Taniguchi said.

( Adapted from To Catch a King by Harry Patterson)
This little lot = this small quantity.

'Lot' here = a distinct portion or parcel of anything, as of merchandise: The furniture was to be auctioned off in 20 lots.
Thank you for the reply.

I got it!
