My favorite logos are Neon Sheep and Crown Paint. I want something sophisticated, but with an edge or sense of playfulness.
Some brands or places whose sense of style I like: Apple, The Ace Hotel, Gilt, Uber, The Standard, Urban Daddy, Fast Company, Tesla, Wired, Bespoke Post, Opening Ceremony ... Most of these brands do a good job of embodying both sophisticated and edgy.
If you're going to go with a predictable writing tool in your image, no quills or fountain pens, please. I prefer a typewriter. Or, do something entirely different. Maybe it could be a typewriter with dollar signs (or even other currency symbols) floating out of it, or something about a lifestyle of wealth that comes out of writing.
For fonts, please use sans serif fonts, and put the name in bold, all caps. The slogan can be in regular font, either all caps or sentence case.
Please, think clean, clean, clean, simple, simple, simple.
