Is your publishing house aware that you are selling your services outside of work?
While I'm sure what you're offering is high-quality, my gentle suggestion is that you check with your senior editor first, before you find a conflict of interest shadowing your career.
Well, yeah, of course she does. She knows about the blog and she knows that I'm looking for other work, even work that would replace the job I have. We've talked about it from time to time.
What I have is a pretty bottom-level job within a two person company, and one of the people is me. It would only get lower if I was an unpaid intern. It's not expected that I'm going to stay working at the literary agency forever. In fact, most people only stay at my position for a year or two, and then the agent (or agents, as many people have multiple jobs and multiple agencies because they need the hours to pay the bills) helps them find a job at a publishing house. It's in the agent's best interest that a former assistant become, hopefully, an editor at a major house, because the agent is thinking that down the line, in 10 years or so, their former assistant may be the person they're pitching a novel to.
I've stayed with the job so long because (1) I was in school full-time until January, (2) I genuinely like my boss and I enjoy my work, (3) until recently I've been too ill for full-time work, (4) I'm a working writer with one book coming out in the fall that's the first in a series and another we're about to try to sell to another company, (5) the job market is completely dead right now.
It may seem a little weird to people who have more traditional jobs that involve getting a job at a company and hoping to get a raise or a promotion that I talk to my employer about job prospects, but people move around a lot in publishing, and it's in everyone's best interest to keep a network of people they know in other agencies/companies. I think when it gets to the corporate level (VP or above) they get extremely secretive about job offers elsewhere, because there actual living wage is involved, but that's at a very high level that most people don't achieve or don't want to achieve.
