Well,I got the same pump and the extra stuff like you,and it cost me 800 plus bucks,about 2 months ago,,just saying they made way more than my guys did,[who do this for a living],did.
When I needed a new pump in an old well I had,I let my figers do the walking as they say,guys who did my other well did not call me back,so,,went searching,not many to chose from here,,three of the 4-5 I called did call me back,,one wanted 1,500 or more,said his stuff was the best,etc,and that was as low as he could go,,next person called me back,said about 1,500,after talking to him for 2 min,,price went down to 1,000-1,1000,,,next people who call,do this basicly for a living[others were plumpers and water conditioner type people also],,he said about 7 hundred,,I said sold,,he said I was number 20 on his list,,two weeks later,,he has it in and working in about 2 hours or less,,charged me 150 labor I think,him and his buddy,,little extra and I bought some fittings,bill came to 850 about...
Now,I have another well,and could wait 2-4 weeks,,so,,,just saying some of these people want 300 400 dollars an hour,for doing basicly manual labor,,because they know they can,,cause you got to have water,,and that ain't an ethical way to do any bussiness,,[welders with 40,000 dollar rigs don't charge near that much,people who do dozer work don't charge near that much],for example,,,also,they bought that pump for a good bit less than you or I could..
