I'm looking for someone to create a fully working HTML5 sip client for me. Has to support calls, messages, presence, address book, etc. Also, has to show remaining credit (I can supply a code for that). Should be skinnable and work on tablet device (no flash).
Bid only if you are 100% sure, you can complete the task. Preference will given to people who have creating something like this before (I would like to see a demo, if possible).
