Just tried a random size (24x36, + 3 inch matting, other things default) and tried to match it in a German manufacturers webshop.
Prices: 180 $ (+ sales tax depending on state, correct?) vs 180 € (= 240 $, includes 19 % tax)
Options: Very similar, german site offered more detailed options for materials (neutral, since to much can be to much) and also for different mounting methods and artwork thicknesses (can be relevant depending on artwork)
I feel like you need to work on presenting why I should go with you as someone new to the market at not-that-much-better prices than an established, well-regarded company which gives me more options and information about their product. Maybe your materials or craftmanship are better, but I have no real indication that this is the case, or the difference is on a level a might care about. Right now I have you calling your competition criminals and then charging more or less the same.
