I'm launching a boutique DIY craft studio in Texas called "Fluff Studio" and need a quote for our exterior illuminated channel letter sign. The design will feature our logo text "Fluff Studio," with front-lit illumination and a soft ivory/cream white face color. We prefer warm white LED (about 3000K) and a letter depth of roughly 75-100mm. The landlord requires no backplate panel, and for wiring concealment, we prefer a slim raceway painted to match the building, staying within the letter footprint. Could you please provide a preliminary quote, suggest a fabrication method, and let me know the estimated lead time? Also, I'm interested in the shipping cost to Shenzhen, China, and whether you've made signs for U.S. storefronts before. I can send the logo and storefront photos once we proceed.
