Assistant

I have three businesses and need help.
1. I am an author and need my VA to contact publishing agents by researching who is accepting current submissions in my writing genre. Follow their specific submission criteria (has to be followed precisely) after the request is emailed, following up after about a week of sending.
2. I have a holistic alternative brand, and I sell organic, vegan, skincare kits, supplements, candles, etc. I need to find someone to carry my line in their spa, dispensaries, health-food store, etc. I need emails sent with an intro letter, product descriptions and costs, and follow-up after the emails have been sent. I need the skincare line uploaded to be sold on Amazon and keep up with what that entails.
3. I am getting my license as a Life and Health Agent and will need someone to keep me organized on my schedule, possibly take calls in the future. Depending on when I increase business, I may need additional assistance in this business.
