I'm about to create a new betting affiliate blog on WordPress. I found a developer here in Denmark. Firstly we'll make a simple website, with few features like betting-tips, bookmaker review and video predictions.

But once this is done, I'll need to add features odds-comparison, sure-bet and other features created by myself like; in-play value hunter and live-stats.

But all developers I've been spoking with, didn't have experience about working with betting api's or in general to create features within betting.
Can you suggest some web developers, that have experience within working with betting affiliate websites?
