Amazon Dropshipping Integration with Book Selling

I've been selling books on Amazon for four years, and I'm exploring the possibility of incorporating dropshipping into my business model, while still selling books via seller fulfillment.

Key Requirements:
- Market research: I need comprehensive assistance in identifying viable products for dropshipping. The products can be from any category, primarily determined by what the research indicates.
- Amazon Expertise: Knowledge of Amazon's dropshipping policies and best practices is crucial.
- E-commerce Experience: Prior experience with e-commerce and dropshipping will be highly beneficial.

Looking forward to finding a professional who can help me take my business to the next level.
