Fix product page & fix other Wordpress Errors

Hi all, I am contacting because my site have a few errors and i cannot sell until these errors or fixxed. I have a wordpress website and I am having an issue with my product display layout. It currently looks very unprofessional and unorganized, and i really need a new template. If you take a look at the attached document, you will see that i i could use some help designing my product display design, it currently looks bad and i just want it to look more professional and more appealing. The image is also oversize, i am not sure why that is, but i could use the help fixing it. Maybe similar to [login to view URL] (image in document). OR anything else, i just want it to look much better than what it is so i accept your ideas! My theme is Nitro([login to view URL]). Which has an easy page builder called Visual Composer so the product template shouldn't be hard at all. So please help me create appealing product design. For more information or in percise detail, view attached document. Thanks!
