OSClass modification

Avg Bid (USD)
Project Budget (USD)
$30 - $250

Project Description:
I am planning to use OSClass (open source classified script) for some project.

I will use 2 plugins in addition to it -
1) More Edits - this gives more options to admin for moderation
2) Custom Fields - this allows to add more fields to classified ad

I want small customization in the code - 2 of the newly added custom fields should not be visible to everyone. It should be visible only to people who have posted & got approved atleast 1 Ad from their account. i.e unless i have atleast 1 approved AD in my account I should not be able to see private custom fields on someone else's account.

One needs to understand how osclass code works & then make this change.

Skills required:
MySQL, PHP, Software Architecture
