After years of buying and returning best men's leather jackets, I've learned to spot quality issues before making purchases. Thought I'd share some warning signs that indicate you should probably look elsewhere.

After moderate success with my historical mystery series in the US market (self-published), I'm interested in exploring international rights and translations. Are there specialized book marketing services that focus on helping indie authors break into foreign markets? I've done some preliminary research and discovered that international book marketing seems quite different from domestic promotion. Some markets prefer different covers, different marketing angles, and even slightly adjusted content. My questions: * Has anyone worked with marketers who specialize in positioning books for international rights sales? * What are reasonable costs for these specialized services? * Are there reputable translation services that work specifically with indie authors? * Which international markets tend to be most receptive to historical mysteries? I've been approached by a company offering "global book marketing services" for €3,500, but I'm hesitant to commit without hearing from authors who've successfully navigated this space. They promise assistance with Frankfurt Book Fair representation and connections to foreign publishers, but I can't tell if their claims are realistic. Any insights from authors who've expanded beyond English-language markets would be tremendously helpful!
