IMO.. If those shops were really concerned about wanting your business, they would've respected your preference for wanting to keep your 06 and perform the engine build for your 3V just as you requested.. Bottom line is if you really wanted to sell your 06 for either a Coyote or LS3, you would've done so rather than request having a shop do an engine build for your existing 3V in the first place.. Seems to me those shops you talked with are obviously just not really interested nor want to be bothered in taking the time in wanting to do an engine build for you, otherwise they would've respected you as a potential customer along with wanting to earn your business in which from their actions just goes to show they really aren't worthy of your business to begin with anyhow..
