We went through a lot of sources, but the best deal we've found for good-quality dried SFL is actually on Amazon. 10lb boxes of Wormsking larvae sell for $50, $45 if you set up a subscription, and are often discounted. Free shipping if you have Prime. Smaller sizes, down to 2lb, are also available. We've been using them for years and have found these prices hard to beat. The birds go nuts over live meal worms, but these dried larvae are not far behind.

Oh, and soldier fly larvae supposedly have something like 80 times (!) the calcium of meal worms, something that is touted as important for egglayers.
No, I don't work for Wormsking!!
