Knowledgeable guy and seems nice enough but he totally ripped me off knowing I'm a young homeowner. Here are the prices he charged me in case you're wondering if he's an honest businessperson:
$500 to replace a bathroom faucet
$200 to replace a shower head (I know nothing about plumbing; he could have told me I could easily do it myself)
$225 to replace a fill valve in the toilet
If you care at all about getting a fair rate, look elsewhere.
