Word Macro Builder

Looking to write a Macro which will reformat/amend a word template document. This will include finding text and changing/inserting new text, formatting different sections (to include bullet points, font type, some words bold and some not), inserting text, amending text. Once written this will be able to be easily applied to the same initial template multiple times with ease of changing the inserted text if need be. Initial template is not large - 3 pages and 1060 words.
