chemical engineering project

I would like the essay to be at about 10,000 words. Also, would it be possible if you could make some drawings on the project. (for example by using the Autocad program or sth similar). The style in which it has to be written, has to be in an academic level. As for the digester, it doesn't have to be big and massive, it can just be in a small scale only to prove the way that it works as a machine. Also, I would like this to work in a United Kingdom environment. Please let me know if you are ok with the above info. ((" Designing a small scale digester for generating biogas from kitchen waste.")) IS THE TITLE. tHANKS!
