I am a college student, that has been making apps on the side since the release of Swift. You don't hear that every day. I am trying to put myself through school, while doing what I love on the side. I have 2 accepted apps on the App Store under my name, have collaborated on other apps that are on the app store, have made a few that aren't on the app store yet, and also, I am the COO of the app Shoe Swap, which is growing rapidly. I know the process of getting accepted into the app store, I know how to develop to meet Apple's very strict guidelines, and I learn quickly if there is something that I do not know. I look forward to working with you!
As far as the other bids that are quite low, and quite frankly, within your budget, you are going to struggle with communication and quality of work. I am here to offer you work at the appropriate rate, all while giving you the quality you are paying for.
As far as your app idea, I am a bit confused on what exactly you are wanting to have done. As you stated, it doesn't seem like your idea is very difficult. The price I have set is not set in stone, but depending on a more in-depth description, could go up or down.
Making the user interface , as well as getting the app accepted in the app store are 2 separate portions of the project, which the price will be TBD.
