App for iPhone

We want to make a Yellow Pages App. We need programmer for a Yellow Pages App that can also do some design. We have the App made up in Omnigraffle, but it might need some tweaks and a few good ideas. It contains: -Customer info -Map -Pictures -Notes -Area search -Forwarding of info -etc. Not too complicated in other words. The App will be offline, but with push notifications when there is updates available. It will be linked to a database with about 10.000 entries in different categories. We would like a team that can do this, at a reasonable time and for a fair price, so we are not depending on one person to complete. Also we have several other Apps in progress so hopefully this can be a long lasting relationship. Looking forward to your replies. Please also provide info of previous design so we see what you can do. A few of our future Apps are quite demanding... Best Regards
