If you take a cabinet door or other representative stained part to a paint store they can match the color. Take samples of the pine trim, too. A good store will show you various results, dried, and let you pick which you like best.
Note that the cabinets have a finish over the stain which changes the appearance. For a quick approximation of this on your pine samples, wipe with water or mineral spirits; or to be nearly certain apply shellac, lacquer, or varnish and let dry.
If you read up on staining you'll also find the finish changes with application technique, e.g., thinning or not thinning the stain, how much it's thinned, how long stain sits before wiping, so you need to factor technique into your comparisons.
Is the off-the-shelf stain price for pre-mixed or custom? It's doubtfull you'll find an exact match in pre-mixed, though it may be close enough - only way to tell is to buy some and try it. Around these parts custom costs more and stores will only do gallons.
I don't know how much trim you have to do, but stain goes a long way, so the cabinet maker's $35-a-quart stain may not be a bad deal, depending on how you want to spend your time.
Just being persnickety here, but pine will never look like maple or maple like pine unless they have an opaque or nearly opaque finish applied -:).
