Get Facebook App Approval for one of my domains For Posting into pages and groups

I need to get approval from Facebook for an app associated with one of my domains, that will facilitate posting into pages and groups. I need an experienced individual to complete the process and ensure that the app is approved without issues. I already have a Facebook Developer account, and while I have previously tried to get approval, I had technical difficulties that prevented me from succeeding. As such, the right person for this job needs knowledge and experience in setting up Facebook apps for maximum approval. This is a must and I look forward to the successful completion of this task.
