Pressure tank size for pressure booster pump setup

Incoming town water, Dave BT20-30 pump just installed. IMpressive increase in pressure and flow. No holding tank yet, so pump cycles on even just filling a glass of water.

Up to a 5 gallon tank can be placed onto the pump itself, no additional plumbing required. Project is already over-budget - I did purchase the pump myself to save $$$ but the install cost was higher than expected (I can't sweat pipes).

With respect to operating costs and pump life, how much of a difference should I expect between using a 5 gallon pressure tank attached to the pump versus a 30 or 40 gallon floor tank which requires plumbing (30 gallon tank is $200 more than 5 gallon tank, plus install costs)?

How much should I expect to pay for a plumber to install a 30-40 gallon pressure tank into the system, given I purchase the (Amtrol) tank?

The cycling of the pump will kill it fast.
A tank for your pump is a must. I would use the biggest one I could find.
The bigger the tank, the longer run time and the longer the pump will last.

The price of a tank can be $200 and up. It just depends on how much you want to spend.
The cost of installation can very. That would be hard to answer.
I would guess 35 to 50 dollars an hour.
