JomSocial Website New Updates

Hi, I'm in the middle of developing a Joomla website using JomSocial. It's up and running but few things are unfinished and my developer is unavailable. I'm looking for someone to take over and make some changes for me. I'll need to add an extra user profile type with different permissions to add extra profile info. Also need to include a payment system to allow advanced profile types to only be signed up with payment subscription (automated system integrated for new accounts, change account and cancel account subscription). I also want to include a blog feature to allow users to post articles. A few other changes are needed to the website including changes to an existing calendar system and advanced search options to find user profiles. The website design needs to be updated (it is a responsive design) - I will provide all design style images to show you how it needs to look so you won't need to do any design, just copy my examples already done. I need someone who can work fast and will also be able to offer more future paid work for all future updates.
