Please help me to write my first novel!

Hello. I am a published author. I have won three local contests for short stories. They have been published by Alfaguara and Planeta editorials. Now I want to write my first novel. The novel will be a gathering of seven short stories. I already have written the synopsis of each story, but I need ten months to write the whole novel, so the money is to pay living expenses. These stories will go from thrillers to sci-fi fantasies. They are very entertaining stories, but always with a social messages that will go from pollution of our environment to the political corruption of some social systems. I will write in Spanish and it will be translated into English by a professional. My favorite contemporary authors are Ian McEwan and Philip Roth. Many thanks!
