Continue a C# Project by writing a simple C# function

I have a project written on c#. The problem is that I have been faced with a problem and I need some help. So, my bot is logging in to one Google+ account from a list, then harvest list of all groups in which the selected account is joined. All I have to do is to post an selected image and text and send these to specified community (Post to that group/community) To make you understand, function which you will have to construct: private bool postImageToGroup(string imagePath, string groupId, string textComment) { // You're logged in in this point. You have cookies and can acccess group page and post to it. // All you have to do is to handle uploading image script and upload image to google server then post to group with an mesage. } Is should take no more than 1-2 hours for an expert. Remember, I need someone very good at C# which know very good how to use HttpWebRequests to upload an image to Google+ Community PS: I will give you the whole project to make it.
