Let me add a few things for your consideration.
o Is it realistic to assume only one antenna? Many on this reflector,
myself included, have designed and installed tower systems with one
multiband HF Yagi, a second WARC Yagi, shorty forty, or rotatable dipole,
plus some sort of V/UHF packet vertical antenna.
o If the final tower model includes the above supplementary antennas,
you'll have increased costs for coax cabling. (Say $1/ft, including
connectors, unless hardline.)
o Mast. (Say $5-$10 per foot.)
o Antenna switch. (Say $100-$200 if available used.)
o Conduit system, steel boxes at either end of conduit run. (Say $200)
o Ground rods, ground wire, clamps or other fasteners. (Say $300)
o Trencher rental to open a hole in the dirt for the conduit and ground
wires. (Say $100-$200)
o Concrete can run you $50-$100 per cuyd and self-supporting towers
usually need more than do guyed towers.
o Crane rental to place tower and/or antennas. (Say $100-$300.)
Your estimates may have included these details, but I couldn't tell for
sure. And yes, the estimates you use should be towards the higher end of
your ranges, below.
