need several minor changes to website code.
hosting / site is PHP/mySQL and is a live existing site with pages using HTML / CSS layouts.
I will provide a revisions list document upon request with full details, 5 items this is the summary, dont bid if you have no reviews or have trouble with english:
1) current paypal post-transaction processing is done via a "results URL". this is an unreliable implementation. REVISE this post-transaction processing to be done via IPN for reliability and robustness.
2) paypal "return URL" post-transaction not functioning correctly. troubleshoot and fix.
3) site currently creates a PDF and mySQL DB entry after successful paypal payment. Slightly revise creation functionality for one table column/field
4) move text from one page to a different page, preserving current page layouts and visual appeal of both pages
5) Paypal post-transaction processing currently includes use of SendinBlue API to remove user from a list, I need an additional API access to also remove that user from an active workflow
