Joomla (JomSocial) Website Updates & Changes (2)

Joomla (JomSocial) Website Updates & Changes (2) Hi, I'm in the middle of developing a Joomla website using JomSocial (this is a directory website for users to create directory profiles). It's already 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 (there are already 2 types created) with different permissions to add extra profile info. Also need to include a payment system to allow 2 of the 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 simple 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 search options to find other 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.
