1. Your catalog, with prices, as a .pdf that I can download and search. Barring that an online catalog in the style of mcmaster/amazon etc.
2. For job shops and other service providers I might seek a quote from - where the F*** are you. Don't hide your location. Which state, city, etc., you are in matters for various accounting and tax reasons, and the distance matters for some projects.
3. For anybody who does quotes - an *email address* that somebody actually reads. Or form that actually works. And it's totally OK to have various schemes to knock down spam. I get it.
4. The more pricing the better. Saying your new 5-axis Unobtanium Metal Deposition Printer and Fabric Cutter is Very Economically Priced could mean $1.8million given the current market. If you won't at least tell me how many zeros in the price, I'll tend to assume the price is very very high and ignore you.
