Looking for a PHP /HTML/API coder

[Gifted]

Im looking for someone to build a simple text box to input a btc address with a button to retrieve balance of a address using

the example shown here in php--->  http://docs.xapo.apiary.io/#reference/deposit-addresses/deposit-address/retrieves-deposit-address

I also will need the example shown here to let clients set there own threshhold --> http://docs.xapo.apiary.io/#reference/deposit-addresses/deposit-address/updates-deposit-address-payment-threshold


The code will be put on this page http://www.bitcoinfaucetexchange.com  and will go right under where people input their email or BTC address.


If you can do this and are interested plz tell me what you will charge and how long it will take. Thank you in advance for your inquiries .  


Note:  most is already written in the example !
