The telling thing is that not one of the people listed in the "About Us" section of the website has worked in the publishing industry. In addition, while their mentoring programe for writers seems well-intentioned, I'd want to know who has used it and gone onto be published by a commercial publisher.
The questions you need to ask yourself nomolos are:
1. Are they paying me an advance to publish my book?
2. What distribution do they have in place and can they put books on shelves in bookstores (whether in Hong Kong, which is where they are based or elsewhere)?
3. What will Proverse do to promote and publicise my book? Do they organise reviews (including ARCs), provide books for signings, help generate interviews etc?
4. If I am expected to get involved in publicity, what am I expected to do and how much is it realistically going to cost me (e.g. in printing posters etc)?
5. How does the royalty scheme work and how much is the percentage?
6. If the only way I can make money is to sell books myself, do I still get royalties on those copies or is the book competitively priced to allow me a margin of profit as against other books on the market?
Although authors do get involved in promoting and selling their book, you should not be the only person doing so and if you're at the stage where you're spending money either buying your books to supply to others or paying for large amounts of publicity material, then you are unlikely to make back enough to cover the expenditure.
Hope this is useful.
