I did her horoscope at Astrodienst using sidereal zodiac and placidus house system. Leo rising
Sun in Leo conjunct Mercury 2nd House.
Venus in Libra 3rd House.
I am seeing strong indicators here of the entertainment and art industries. Sun in Leo gives a proud, humorous, and easy going personality. Next to Mercury, it may be that this person finds it difficult to concentrate for long periods of time, so they like a lot of action when it comes to work, rather than sitting in some room by themselves or behind a desk without human interaction. Because the sun is situated in the 2nd house as well as Mercury (business), I see fields such as publicist, agent (for athletes/actors), catering, wedding, event and party planner, real estate, and art auctions. Vocations that let this person socialize but also allow them to promote others.
Moon in Scorpio conjunct Uranus 5th.
Neptune and Mars in the 5th.
Again, emphasis is placed on leisure and her focus is on things that give other people pleasure. I don't want to suggest some controversial options but go-go dancer comes to mind. If this isn't her cup of tea, then she could try acting or arts and crafts. I do think she will do really well at having a social media presence, i.e., marketing her services via Youtube, Pinerest and other popular media online.
I'm not sure about writing but I think as long as it is light, fun, i.e., children's books. However, I get more of a vibe that she will want to work with adults.
Aquarius in the 7th House.
The people she associates with will be technology savvy, original, freedom-oriented, and looking for new ways to express themselves. They could even be humanitarians working for environmental nonprofit. Again, I get more of a pleasure vibe - night clubs, concerts, casinos, LGBT night life.
Strongest impression is the arts. With Moon in Scorpio - spiritual, dark art - i.e., horror industry.
MC in Aries and 10th House Libra/Aries
Again, a job with socializing, lots of it. See above for ideas.
Let me know what you think.
