Hi Ben,
I have placed a bid, however I require clarification - do you expect all 13 books to be done for that price, or just preliminary sketches? Also, how long do you anticipate each comic to be? If it's all 13 books, coloured and finalised and they are more than 10 pages then I will need more than 2 months to complete the job, as the colouring process can be a long one, even for professionals like myself!
After further discussion on style and characters, I would usually provide my clients with preliminary sketches, then once they are agreed upon, I would continue to work from there. I keep my clients in the loop at every stage of the process.
Further price/time negotiation may be required on this job as it is a big one, however, if you want a native English-speaking professional for this job, it will be well worth it! Contact me today!
