Good Evening,
I am quite confident that I am capable of adding the desired functionality you require within one to two hours while staying under budget.
I am an experienced web developer with 6 years experience with design and functionality. I am quite familiar with most technologies used in web design such as HTML, Javascript, jQuery, CSS, Bootstrap, MySQL, PHP and Ajax.
Should you award me this project, I will make myself available via Skype and email should further communication become necessary.
