Where can I find steps to repair evap vent solenoid & broke engine mount? on 2006 Chevrolet Impala

Dealership wants over $1500 for repairs to replace broke engine mount, replace evap vent solenoid, oil filter adapter housing gasket & pressure control solenoid (code p1811 max adpt long shift.) I have a guy that said he'd fix if I buy parts but I'm not sure how involved and/or difficult the repairs will be. He said most of time somebody mechanically inclined can make repairs if given steps or guidance.

that sounds very high get a 2nd diag and est
I thought it sounded very high so I told them not to do repairs. Problem is I'm already out $80 so far....what if someplace charges for diagnostics and they're cost is the same.
that sounds very high call a good mech and ask what it would cost to replace those 2 parts in your area and give you an est over the phone. my area may be different in labor rate than yours
