I don't know if it is allowed to suggest some seo tools.. But I will do. Most SEO Consultants use SENUKE XCR. This tool generates a lot of quality backlinks without good efforts But it is a much expensive so I suggest you starting manually until you get some cash and then try to invest like a professional. don't forget that investment is important for getting, Giving and getting and there is a win win situation for all the world parts.
