Complete and upload ipa to app store

A few months ago I had an IPA made for my website. I have the IPA, and I also have an active Developer Account with Apple, but I can't seem to put the two together properly. The IPA seems to have signature problems and I have no idea how to resolve this. What I require is the IPA file to be reviewed and if required updated. I then need the file to be submitted to the APP store using my developer account. I would also like to ensure that the APP is approved so if there is any work required on the IPA to do this then I would like you to include this in your costings. To be clear, I will not complete the project until the APP is successfully submitted to the APP store. Please answer this question to show you have read the brief. What is ten minus nine. Thanks
