Is it possible?

I am trying to do a 1 time purchase for Pro-Sites and I am trying to redirect the customer upgrade and account links (Current Pro) to a page with my pricing table. (I do manual payments only)

Is this possible?

References:
<a href='admin.php?page=psts-checkout

which references:

function scripts_checkout() {
	  wp_enqueue_script('psts-checkout', $this->plugin_url . 'js/checkout.js', array('jquery'), $this->version );

I do not wish to lead my customers to the tables for the monthly rate or the table that is included.

Thanks in advance!
