Braintree payment processor for ubercart

I have a site all set up and ready to go, but I had to use a payment processor outside of what current drupal modules support. I am looking for someone who can help hook up http://www.braintreepaymentsolutions.com/ they say they are vey developer friendly and there customer service so far has been great. I have a couple of days before I get my account info from them and this is my first time getting outside help. I am running ubercart. How long does it take usually take to create a payment processor module? Does anyone have any experience integrating Braintree solutions?
