PHP script to modify a TXT file

Hello. I need a custom script written to process a TXT file. Please give me a quote and when you will be able to complete this gig. I need this completed as soon as possible. If you do a good job for a fair price I have several other gigs for you. Requirements are below and there is an example input and output txt files attached as a ZIP. Script Overview 1. Process a TXT file stored on the server in the same folder as the php script 2. Display the results in a basic web page with a "copy to clipboard" button Purpose The goal of this script is to take an article that has multiple paragraph and sentence variations and output an article with random paragraphs choosen and sentence variations put in standard jetspinner spintax. Definitions... Sentence Unit • The input TXT is formatted with each sentence on it's own line. • Each of these sentences is rewritten several times with each new version on a new line. • At the end of the sentence rewrites there is a new line with the tag "#S#" denoting the end of that "sentence unit" Intro Paragraph • There are multiple intro paragraphs. • At the end of each intro paragraph after the last "sentence unit" tag there is a new line with the tag #IP# denoting the end of that "intro paragraph". • An intro paragraph is always used at the beginning of the output article Concluding Paragraph • There may or may not be concluding paragraphs • At the end of each concluding paragraph after the last "sentence unit" tag there is a new line with the tag #CP# denoting the end of that "concluding paragraph". • A concluding paragraph is always used at the end of the output article Body Paragraphs • There are multiple body paragraphs (usually 15) • At the end of each body paragraph after the last "sentence unit" tag there is a new line with the tag #P# denoting the end of that "body paragraph". • Body paragraphs can be used anywhere in the article except as the first or last paragraph • If there are no concluding paragraphs, a body paragraph can be used as the last paragraph Double Line Break • Some paragraphs in the input TXT contain the tag #SB# • This should be treated as a double line break in the output TXT • The point is to make a single paragraph unit look like two paragraphs HTML Lists • Some paragraphs may contain HTML for ordered or unordered lists. • When a <ul> or <ol> tag is encountered there should be a line break preceding it and each <li> should go on it's own line. Random Processing • Randomly choose one Intro Paragraph • Randomly choose 4 to 6 Body paragraphs • If present, randomly choose one Concluding paragraph • Assemble all sentences within a sentence unit into spintax format • Assemble sentence units into a paragraph Additional notes • Sometimes there are two sentences within one line but this should still be treated as a single sentence that stays together. The line break is the delimiter. • The number of sentences per paragraph in the input file varies
