I linked to some dichloromethane suppliers that sell to hobbyists.
But butane is less toxic, won't dissolve your vinyl floor or countertop, is cheaper, and easily available.
Also, because room temperature is 25 degrees above its boiling point, it is easier to get all of the solvent out of the product without heating it.

Like I said, HPLC is way beyond my capacity; a single HPLC device would bankrupt me, not to mention the cost of columns, mobile phase reagents, etc :I
And by hydrophobic I mean "will NOT mix with water;" stuff that will form a layer with water. Imagine vegetable oil floating ontop of vinegar.
But believe it or not I found some suppliers on Ebay that sell Dichloromethane; some say they only sell to registered business and university labs, some don't.

Methanol boils at 68 Celsius. Perhaps ethanol will work instead of methanol is too hard to get ..... Everclear is 190 proof / 95 % ethanol and will boil about 78 C. Alcohols are commonly used to extract colors and flavors from plant material.
If by hydro phobic solvents you mean polar aprotic solvents - look at nail polish removers ... perhaps you can find bulks at salon supply stores?. Nail polish removers are typically one or more of ethyl acetate, acetone or acetonitrile. Any of Therese would extract your terpenes (saw more recent post).
