Hi, i have read your project description, i understand what you want, and i would like to offer you my services. I have strong knowledge of all required technologies (IE, WP, WP Contact Form 7), plenty of experience with them, most importantly including cross-browser issues knowledge, and experience with fixing bugs in all of them. I will need to know the IE problematic version(s), and temporary access to your website via FTP or alternative to get this fixed. Feel free to contact me by private message to discuss the details of this project. I'm looking forward to our cooperation.
