I need printing services. So, I'm ready to pay well, just to get a good and high-quality print quickly. All this is required in order to promote the business.
I'm sure you can google it and pretty quickly find a good option for your purposes. I've never needed printing services, so I can hardly recommend anything specific.
Do you have any specific ideas? Now there are many opportunities to create something custom, and this is a wide scope for creative people. Not so long ago I found the online service Printsafari, and it was very useful, because I needed high-quality catalogs to present my business. The site https://www.printsafari.com/us_en/catalogs makes it easy to create a template, edit it, choose quality paper and all that. It doesn't cost too much though.
