Please only award me this bid if you're open to the following feedback.
Bootstrap works with Wordpress, it uses HTML5, and it can seem appealing because of it's sleek and mobile-friendly design, but it doesn't use PHP. Other options that use PHP will be able to create better, more beautiful, and more friendly experiences for you later (so that you don't need to hire someone for EVERY tiny edit you make to the site)!
If you're open to discussing the best fit for your goals- instead of restricting it to one option- please contact me to discuss your needs in more detail.
[I am a web DESIGNER, which means that I build BEAUTIFUL things using tools created by web developers who are less attuned to aesthetics... that is of huge value to you, because you don't want an ugly website that you need to call a developer to make minor changes to!]
