Good question.
I am primarily a writer. I've written erotica for several years, and have been seeing an increase in exposure for articles and advice columns in recent weeks. I can also write press releases, email advertisements, and newletters as needed.
I am consistant with pricing, giving good discounts to those who wish to purchase stories in bulk, and have a great turn-around time of less than two weeks depending on the order recieved. All content written is twice-proofed before sending out, and can be downloaded from my server or sent in an email.
Recently I've started dabbling in photoshop and have created some nice galleries. Once I become more comfortable with my skill as a designer, I'll be offering site and gallery designs at reasonable prices.
