OK, here are my two cents,
6th house in Taurus, 10th in Virgo:
Ruler of 6th, Venus, In Leo, 9th house; Ruler of 10th, Mercury Virgo in Midheaven:
Venus in Leo is related to a career in arts, theater or other kind of artwork. Considering the earth quality of your work houses, and this Leo Venus, I'd say you could get engaged into something related to production (taurus, virgo) of shows or plays (leo), cultural production in general. Scenery, art direction, anything that has to do with art (Venus in Leo) objects (Taurus). Antiquary, art gallery, cosmetic industry, etc.. The conjunction of Venus-Sun in Leo might point to acting, but the earth points (cusp of 6th and 10th; Mercury in Virgo conjunct Midheaven) indicate that you may get involved in other areas of entertainment projects, like finances and production.
The difficulties you face in stablishing yourself in a job (which probably is very disturbing since your earthy work houses need solid ground to step on) may be related to bad choice of partners (Venus+Sun+Mercury in T-square with Saturn in 7th and Jupiter+Neptune on Ascendant). Maybe a lot of promises (Mercury square Saturn in Gemini) but nothing concrete in the end (Neptune contribution...).
Moon conjunct Pluto in 10th in Virgo point to assisting people in power, like company directors or managers. A marriage to a co-worker is also indicated (maybe already happened).
The choice of co-workers is what will determine the success or failure of your career path. Good criteria to select work partners would be when they are very clear and straightforward in terms of salary and function. If there is too much talk and promises (Mercury square saturn and Neptune) and not enough and prompt material evidence of seriousness (Moon+Pluto), beware.
I think i may add to your confusion with all the options, but it is indeed a bit difficult to determine career through a chart. Sometimes the career is determined by the ruler of 6th or 10th, but is sewed with qualities of all planets and signs involved in work houses, which in your case are a lot. This "a lot" also may point to many different works through time.
