I have a theme that is working very nicely but the calendar is terrible. There is coding involved with AJAX so this will be an issue. I have NO time for you to look it over and make mistakes on the site. Either you know exactly how to work on this project or you don't. If not - DO NOT BID! I will leave a 1 star review for blowing up my website, and I am serious.
Again, you are going to change the "look, feel, and flow" of the current calendar on my site to be more user friendly. I currently have someone who is working for me that is doing great work - but this project is over his head and we both agree I need someone else to step in and customize this.
