Is it possible that form designed using jotform will be good enough to send mails to inbox?

The problem with the order form on my website at: Australian Assignment Help is that the mails are landing into spam and I doubt it might be because of order form coding done on my site. 

Will my problem be resolved if i design the order form using Jot Form. Please help

We cannot guaranty that some emails will not land in your spam folder. However, if this happens you can mark those emails that are coming from @jotform as not spam, to prevent similar issues in the future. With JotForm you can also use your own email address as the Sender Email.

I would suggest you to create a JotForm form and test it to see if you are properly receiving the Email Notification.
