Customize Gen4 PTC Script

hello We own a website, that uses a script from [login to view URL] that we need some custom work on. These will be some rather large additions to the way the current script works so it would help if the potential programmer had some previous experience with PTC (pay to click) software but remember we don't want nulled script we need custom made script with design user panels must be user friendly also provide cronjob file with it we can get many bids but with samples and good looking effects with strong security interface for mysql will be entertained. we have many other projects also 1st project on trial bases so bid as low as u can. thanks happy bidding
