CopyWriter for a new service description needed

dear freelancers, i used a proffesional to create my investment document. the only problem now it that the section in the document where i describe my solution/service,the most important section in this whole document - not very good a clear,the language is pretty poor and with grammar mistakes. so what i would like you to do is to read the text,only about 300-400 words, understand the idea/concept behind it..and completly rewrite a new text which better describe my idea and in more depth..i want this section to have a wow factor.. the new text should be about 500-800 words. I am ready to pay more to recieve the highest quality, so please take that in consideration(for example,investing double/triple time on it,etc) ASAP - tight time considerations
