Overpriced Pine Paneling Project?

[Kyler J Sloan]

I am new to handling renovations, and was hoping for some advice regarding the estimate I got for my next project. 

My current contractor has completed two jobs for me in the past, and overall does good quality work at a modest pace (we ended up going a week past our agreed upon completion date on the second job). 

While I would like to remain as loyal as possible to contractors who have completed work for me in the past, the pricing may be a bit high. I realize this is to be expected, considering the scarcity of free contractors and distance he has to drive from the job. I just want to be sure it is not absurdly more expensive than I should expect. 

The estimate is for 15 K, and includes the following (see pasted images below). 

Thank you in advance for any advice you can provide.
