Broken form elements

Hello CSS gurus

Need a quick help in formatting a form.
Please refer the form in the link below

http://paintology.localgetsvocal.in/corporate-events/
Code (markup):

Here I need to set the following
1. Gap between 2 radio options to be increased (Virtual and Office)
2. "Estimated no of people" is actually a dropbown, but does not appear like one.

Could anyone here please help me set the form right.

Thanks
