As-above, truly simple anyone-can-do know-how [with-で] sufficient profit [and-と] customers [topic-は] can-secure [explanatory-のです]!

Marketing/sales-pitch register. 以上のように ('as above, as described above') is a formal discourse connector pointing back to previous content. Two attributive phrases — 実にシンプルな and 誰でも出来る — stack before ノウハウ, both modifying it. ノウハウ is a loanword from English 'know-how.' のです (explanatory/emphatic ending) combined with the exclamation mark gives the final assertion its pitch-like force.
