I need a simple wp plugin which allow people to compare costs of money transfers from 15-20 websites. It needs to show how much they will receive from each company when transfer. This plugin will need to take current currency rate from all this websites (I don't know if they provide it) and calculate final amount (all cost from each website deducted automatically) which will be received for each company. People then should be able to choose best option and it would automatically redirect them to that website

I need to be able as well to make changes (rates, fees etc.) in this plugin so it can be up to date all the time. Would be even better if it could do it automaticly.
