Greetings, well, in general in the search engine is quite a lot of useful information on this subject, so you could start and independently see the options for articles and information, and then, in case of failure and the forum came for advice. Of course, if you have already tried to do so, but could not find anything optimal for you, then personally I can recommend you to read interesting information about ViOil and in particular Victor Ponomarchuk on the site of the project "Owler". All full information about the company is posted there, so I am sure that after a detailed reading there will be no questions left. Good luck!
