Be able to write code to generate pdf document reports for event managers and web admins having a facebook account managing a facebook event group [login to view URL] needs to connect to even manager's Facebook account, grab some info in excel format(optional) and from there and generate PDF file report of event attendees with that info. Please give me a one time product quote. Not looking to hire on an hourly basis. Payment will be made at the end of product development and all revenue from the app will be mine. NOT LOOKING TO SPEND MORE THAN $200 for this bare minimum functionality app. Development price non-negotiable. "DO NOT" bid if your price is higher. I have the fully functioning android app source code. iOS I have 70% code. Only PDF WRITER in english, chinese, arabic and a couple of other languages FOR iOS ONLY needs to be implemented. I have already spent $850 on this app source code hiring 2 other previous developers who only did 80% of the work before abandoning it - so my patience is low so DO-NOT WASTE MY TIME. Good technical knowledge about facebook login screen, android, iOS SDK and pdf layout/pdf document creation is absolutely necessary for this project. Previous experience in the same technologies preferable. Time is not a constraint. Budget is. Total budget : Fix android bugs : $75 Finish rest 30% of iOS code: $275 Total : $350 If quality of work is satisfactory AFTER alpha and beta phase testing : $50 Total : $400 No tips, bonus ect. FIXED BUDGET. Previous developers code is of good quality with proper comments and documentation and is worth the $850 I have already paid. I am a java coder/developer myself ( just not an app developer) so I KNOW it is of good quality. Developer Needs to know both android and iOS.
