Automated email software

I run a company that provides exotic animal handling experiences to schools and parties.
I have 10 employees who are based across the UK
I receive around 80 email enquiries per day

I am looking for a programmer who can write me some bespoke software which will do the following

– check gmail enquiries from customers
– calculate which of my 10 presenters is closest
– calculate travel costs based on the distance
– reply with a standard email and include the travel costs.

If you can help with this please contact me.

Regards,
Matt
