I'm an iphone developer from the UK. An app like this would normally take upto 5 days given the right access to the information from the web server.
There's very little chance you'll find anyone willing to do it for $75. Personally I would charge more like ยฃ500-ยฃ750 (~$815-$1225). And even thats me being generous. The company I used to work for charged ยฃ600 a day for iphone development.
I'm sure you could probably find someone who can do it for cheaper, but I think $75 is a little optimistic. Sorry.
