About this gig

Finishing a manuscript is a major achievement, but getting it ready for literary agents and publishers requires a different set of skills.


Many promising manuscripts are overlooked because their query letters, synopses, submission materials, or presentation fail to capture attention. I help authors create professional submission packages that clearly communicate the value of their work and increase their readiness for the traditional publishing process.


My services focus on helping authors present their work effectively while identifying areas that may strengthen their submission package before approaching agents or publishers.


Services include:

  • Manuscript Evaluation
  • Query Letter Review
  • Synopsis Development
  • Book Proposal Review
  • Literary Agent Research
  • Submission Package Assessment
  • Publishing Readiness Review
  • Author Guidance & Recommendations
  • Traditional Publishing Consultation
  • Actionable Improvement Suggestions


Whether you're a first-time author or an experienced writer preparing a new project, I will provide detailed feedback and practical recommendations tailored to your publishing goals.
