Need an expert in Google App Engine..

I am looking for a Google App Engine Expert. If you have no experience in Google App Engine, do not apply. We have a Scrabble-style iPhone application where the backend is powered by Google App Engine. We need to ask some very very very basic questions on Google App Engine such as: + How to use this app engine...we need some one to explain it to us. + Google sent us an email stating Python is going to be upgraded soon...how will that affect us? + How do we take a full snapshot of Google App Engine database for backup? + One of our features has just today stopped working on our iPhone Application, we need someone to take a look at why this may have stopped. + Is it ok to delete rows without affecting anything? + How to use the GQL? We need to sometimes find a user or sort by a column for feild... + Is there a way to generate the database layout? + We got another email from Google App Engine Program Manager today that says something about Datastore default auto ID policy is changing to distributed? That email is completely gibrish to me. these are the questions we need to ask a Google App Engine Expert. Then we need to find out why one function of my iphone app has shut down.....is it too many records in the datastore?
