Write some Software - Facebook App

We are a charity that needs a Facebook app developed. We are seeking a quote for two options: Option 1. We want people to be able to sign up to a campaign where they can ask their Facebook friends to sponsor them to travel a certain number of kilometres. Friends would donate a $ amount for every kilometre travelled. We would want to securely collect the name and email address for each person who is travelling and for each of the friends who sponsor the travel. We would also want the travellers to be able to upload pictures of their trip to share with their friends and other app users. Option 2: All of option 1 plus the ability for the traveller's travel to be tracked on a map for their friends and other app users to see. Please provide quote for cost and expected timeframe for app development. Thank you
