It depends on the order but most book covers, album covers, and movie posters take 2-4 days. A film campaign that includes gathering reviews and/or sending out a press release takes 7-14 days. Gigs that require extensive writing and proofreading, such as turning your screenplay into a novel and vice versa, average 4 to 6 weeks (but are usually done sooner).
For gigs under $1,000 I do require upfront payment. Gigs over $1,000 may be split into 2 payments. I prefer Venmo or PayPal, but am open to other arrangements.
My colleagues and I have spent years building our credibility and maintaining excellent reputations as critics. Therefore, one cannot "buy" a positive review. We're going to call them as we see them. However, reviews will be fair, balanced, and never mean-spirited or excessively negative. My goal is to celebrate and encourage indie creators who are producing quality work.
