Figure around 2500 plus or minus. Usually they'll recommend replacing the wire "while in there" and that can add 500 bucks depending. I usually pass on that. I'd only use a Goulds or other known brand, not tractor supply.
I had a well guy out recently. We got to talking about pressure tanks. He told me that the EPA changed the regs on what could be used in bladders and they've had a run of the expensive Welltrol's failing in half the normal time...obviously not your current issue.
