Simple Plugin

I need a simple plugin made for Chrome, IE and Safari. The project details are defined below: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX Goal: To create a plugin for Chrome, Safari and IE that implements following steps: Step 1 - $200 Modify an HTTP webrequest. If this turns out hard or impossible to implement, then figure out a work around such as blocking the webrequest and creating a new modified one, if possible. One scenario where this needs to work on is Gmail Attachments. Modify the attachments of emails before uploading. Step 2 - $200 Modify an HTTP webresponse. If this turns out hard or impossible to implement, then figure out a work around such as blocking the webresponse and creating a new modified one, if possible. One scenario where this needs to work on is Gmail Attachments. Modify the attachments of emails before downloading. *********************************************** If above steps are unsuccessful for Chrome, you may try the below steps: Step 1 - $200 Monitor and cancel an HTTP web request of file upload and create a fake one with modified/encrypted file content in Gmail. This should occur in Gmail only while user actions such as attaching the file in an email, etc. Step 2 - $200 Monitor and cancel an HTTP web response of file download and create a file in the modified/decrypted file content in the folder where all files are downloaded to. This should occur in Gmail only while user actions such as downloading an attachment from an email. This step assumes creation of a chrome app, and integrating the extension into the app, or creating seamless communication between the app and the extension. *********************************************** For 3 plugins: $1200 in total XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX This project is for a trusted client. No milestones or upfront payments will be created until the project is completed, and tested by the client, and until the client is happy. Whoever bids $1200 or less will be hired immediately.
