Hi there!
I see that you have an app ready for publishing. Well, Congrates for that!
I read your project description and I think I can help you out as an experienced iOS Developer.
To publish your Cordova app on iTunes, we will have to attach the code in Xcode, sign it with Apple's Distribution Certificate, and publish your app on iTunes. I do this on a frequent basis, so I can do this swiftly.
I don't think that it would be possible in just one day, because I know how iTunes work. Approval takes time. Hence I'm bidding for 7 days. However, if we are lucky with approval process, we might do it in 48hrs.
Please get in touch and we can discuss it further.
You can see my profile to check my credentials, portfolio and experience.
Looking forward to hear from you :)
Thanks and Regards
