Yep -- Bussard Bros delivers very nice compost to me for somewhere around $20 (maybe $22) per cubic yard. If you're getting a lot (10-20 yards), you can probably talk them into sending the kid with the bobcat to move it around. Their cubic yard "scoops" are quite generous, too.
Free is great, if you can shovel it and haul enough to make it worthwhile. Also, handle "free" compost and mulch with gloves if you're sensitive to poison ivy, because you don't know what went into it.
'Reugan' is a very nice variety, Mike! It may violate your single-species plan, but alpine strawberries make a nice border, too. They don't runner, so they are well behaved. Give them room for best growth/fruiting, once they're planted out.
Here's a great set of growing tips for alpine strawberries:

If you ordered a 120 plant tray, they will be fairly small "plugs." I wouldn't put them straight into the garden. Instead, I'd pot them into 4" (quart) pots... maybe even start them in 2" pots (or 36 count sheet pot trays) and then up-pot again. Just had the thought that quart size yogurt containers with a couple holes in the bottom would make fabulous pots -- the light color will be a plus. 120 of them would be a lot of yogurt or cottage cheese, but you might be able to "dive" at the recycling center. Hoe a trench or two in your strawberry bed and line the pots up in the trench so they're at least half below the soil surface. That lets them soak up water from the surrounding soil and also helps keep the roots cool. Putting the pots in continuous rows means easier weeding while the plants are little, too.
When the roots fill the 4" pot, you can plant them out or even up-pot again into trade gallon pots. If you wait until fall (good time for transplanting with minimal shock), the roots may have grown out the bottom of the pot, but no biggie if some break off in the process.
