The estimate includes:

SOFFIT VENTS
Install ten (10), 6" x 16" size, in client selected color screened soffit
vents in overhangs.


Nowadays 16" or more attic insulation is required by code. It may be
difficult to prevent the insulation from blocking the air flow from soffit
vents. If you install baffles to hold the insulation back you may be
putting a flow of cold air next to your ceiling. A cold spot on your
ceiling allows mold to grow. Might be better to install roof vents just
above the insulation at the bottom of the roof and again at the top. When
you have continuous venting at the soffit and ridge the venting can be
reduced by 50%. Since you do not have continuous soffit venting a ridge
vent may be undersized by 50%.
