Hey Nick, There are a lot of variables, so it is pretty tricky to estimate anything with accuracy for a particular app. The best you could probably do is come up with some really rough figures. All of the current rates are listed, so there is not a lot of mystery to that. If your app is pretty straightforward (like it sounds) I would mock something up and do some testing to get actual numbers, then extrapolate to get your estimates.
Also, I would suggest estimating cost based on 'average' to 'worst-case' scenarios though. So if your serving handler is using between 500ms and 3000ms, with an average of 700ms I would use some number(s) between 700 and a 1000. Also, with your data do not forget to account for all of the meta-data and indexes. If you are expecting to have 1Gb of actual data you might want to (at least) double or triple that when estimating.
