Ok, this is a pretty vague idea with specific requirements.
I've written a guide for a popular online MMORPG that is free(ish) to play. The game currently has just under 200,000 players; showing steady growth and guides sell well. I want to sell this gudie for between $8 and $10 and will give a percentage of sale to anyone willing to work with me.
The guide has no website, no nothing, so some innovative thinking could be required.
Let me know what you would do and how quickly results would start to show. If things go well with the sale of this guide then more guides will be forthcoming.
