Hi.
I'm currently working in a web development company and so far i worked with html5, css3, jquery, simple javascript, json, php, requirejs, java and Wordpress.
If you hire me i will fix the form very quick. Giving the fact that i'm fixing the bugs on 5 websites in one day, i think your job is very easy.
I assume that the form you are talking about is the one on the left on your homepage. With a little css this will be fixed.
But it will be better if you provide me some informations related to your bugs.
I'm waiting. Cheers.
