Most cement/concrete guys are in terrible shape at the moment, they will be
happy to deliver minimum 3 yards. They will make delivery charge, so try
and pick a company close to you. Concrete pump people do not charge
transport here anyway.
Telephone a few different companies and tell each one that you have phoned
around for quotes and you may be surprised what they will do.
Even in California here I had 3 yards delivered and I had a concrete pump
guy to pump the concrete into the hole. The cost was around $900.00 total
for pump, Concrete and delivery. I can tell you the pump guy earned his 260
bucks with 30 minutes preparation and 30 minutes clean up time plus 15
minutes to pump the concrete 50 yards. If you do use a concrete pump you
have to let the concrete people know so that they can use smaller round
stones.
Usually if you have the concrete delivered they will wait about an hour or
less (ask them for their waiting time) while you wheelbarrow it to the hole
and charge waiting time which is expensive after that time. For some reason
if you use a concrete pump they will stick around for as long as it takes
with no extra charge, maybe it is because the concrete delivery guy does not
have to do much work when you pump concrete. With wheelbarrows he has to
keep opening and shutting the valve for an hour.
If you have concrete left over use it to make something like concrete
weights. Put it in plastic buckets that pool tablets come in and make a "U
shape" out of left over re-bar to make a hook and put into the center of the
concrete filled bucket. When it is "set", a couple of them make a great
cheap counter weight for a tilt over tower like a LM-470.

There is such a thing as a false economy - but I think
it would be difficult to finish 2.5 yards by hand, in a
timely manner. Such a pour should be done in one shot,
that is going to be tough.
If you have any value on your time, adding the cost of
materials, etc, you quickly cost more than the price of
redi-mix.
Although some places have a 5 yard minimum, most of
those will deliver 2.5 yards, with a extra delivery charge. Most
of the places I have bought concrete in the past 6 months,
NY, PA, OH, MO, and OK, have been right around 75 bucks
a yard, plus a delivery charge for under 4-6 yards.
Cheaper to call them for me!
