Can you share why you want to reach them? Give a little, get a lot.
I'd like to reach out to experienced professionals and offer them the proposition of joining my marketplace as sellers. I would like them to have worked for 5+ yrs, so they have the skills and business insights to build quality, relevant documents. I think my value proposition is more attractive to unemployed folks, since they're in need of money and have time on hand to create documents.
Let me know if you need any more detail.
