There a couple of good Facebook groups that post a lot of free files, you need to check them everyday as I think some are limited time only. I create a lot of them within the limitations of Easel. Although I like easel and have figured out how to do everything I want to do using it. But also get starting points from Etsy and Facebook. Abut 50% of the Etsy files are crap if you buy the cheap ones. The ones from the more reputable groups that are doing metal and CNC work are good.
The Beer Sign was on Free CNC Art Files.
The Cincinnati one I finally found on line but it was too complicated for Easel as it was made to look old and rustic. . I took a picture of the sign (it was hanging in First Watch restaurant). I sent the picture to a guy I use and he created me an SVG file of it for $20. He is in Pakistan when complete he sends pics for approval or modifications if needed then I pay-pall him typically $20 to $25 depending on what he quotes and after payment he sends you 4 or 5 file types to work with his name is Salman Shakil Profile pic is blue shirt with sunglasses. He has done 2 police badges, Cincinnati and the Airforce Intelligence logo for me.
And yes Oramask and Paint
