Integration work between vBulletin and SkaDate

Dear developers, Hi, I am looking for someone who is able to program an integration patch to move my existing vBulletin platform into new SkaDate software. Preferably, the integration should be cross domain, but in the worst case, I would accept a domain move as a last resort. I will require you to be able to move and merge existing user data from my vBulletin platform to the new SkaDate software. I wish to shift my main platform to Skadate, as such, all data extracted should be functionable on the SkaDate platform although, reflected on vBulletin. Here are the specific functions I require from this patch: Single Sign On, Share Session and Notification Merge. The patch much also include a function to unify Private Messaging systems using Oxwall and sync Avatars. Also, I require you to detail each step of your developmental process, as well as full access to the final code when done. Required experience with SkaDate and Oxwall is needed. Thank you for your considerations!
