Customize Existing Mobile Commerce Application

We are looking for a developer/programmer to customize and tweak existing software code for BarCode mobile reader and BarCode creator mobile application. The applications to be modified will likely include [login to view URL] for the BarCode reader application and [login to view URL] for the Bar Code Creator application. The application must be able to scan Linear Barcodes such as UPC, and Matrix 2D BarCodes such as QR BarCodes (as shown in [login to view URL]) using a smart phone device. The developer will need to evaluate the code and report back so we can determine the degree of customization required. The application should have a simple GUI and be optimized to both Android, version 2.2 and later, as well as to IPhone, IPad OS's, etc. Examples of similar applications include: BeeTag, NeoReader, etc. Code must be clear and concise. Applications will need to be integrated into a product's page on the company's website. If the 2 open source code projects are used developer must have experience working with Perl, PHP, and graphics as required.
