Secure my website

Cancelled Posted 5 years ago Paid on delivery
Cancelled Paid on delivery

My website is wrote on PHP but as of recent we have had vaunerabitues brought to our attention. We have found that things can be changed by the end user using inspect element to alter anything they want and the site recognizes it as fact. So say a user wants to transfer money from one account to another, when the page loads it will not let them type more than their available balance. But they can inspect element and make it 50x higher and their old account will just be negative.

We also have seen SQL injection issues in fields such as where clients can update their email address.

I need someone to go through my site and make it secure from these types of attacks. The entire site consists of about 15 pages.

Lastly I have a problem with my website and PayPal integration. Customers can select a $100 package on my site, and change the currency to for example 100 pesos and still get the $100 perk for their $0.50 purchase. I need this to only accept USD
