New to business -- Residential Demo Bid

I am a young guy who started contracting on my own 2 years ago. I've been plowing snow and looking to add demolition and dirt work to my business. This is a job I was asked to estimate.







This is a six bay garage. There is a block wall on each end and in the middle made of 8x8x16 blocks. The walls are about 11' high and 20' deep so about 250 blocks per wall. This makes about 26,000lbs of block to get rid of. I can rent a heavy material dumpster 10yard / 20,000lbs capacity for $425. The rest of the structure is lumber and barn steel. Thinking maybe a 40 yard / 10,000lb dumpster for $589 (Hopefully big enough).



My estimate was



$525.....................................heavy dumpster (+$100)

$689.....................................light dumpster (+$100)

$100....................................mobilize backhoe to site (half to an hour drive)

$1000..................................10 hours of backhoe with me operating (rental cost $40/hr)

$400.....................................10 hours for helper labor (I pay him $20) ($20/hr for me)



$2,714 Grand Total.



Any comments on this bid? Thanks for your opinions in advance.
