Build on an existing website

I am looking for someone who can add a number of features to my existing website. It was built by my previous developer using Word Press. I need the following features to be added. ONLINE STORE Our previous developer started to build this feature but I am unsure as to just what is need for it to be competed. We want our venues to be able to list any merchandise they may sell and take direct payments for these through our site. QUICK STATS On the search results page we want a drop down added to each result which will show 'quick stats' so the end user does not have to go in to a full profile to see all details if this may not be what they are looking for. Quick stats would include things like Wheelchair access, dance floor, live music, live sport etc... SPECIALS BOARD I would like a chalk board added to a venues main page where they can list the weeks specials. Mainly for use by restaurants, pubs and bars but other venues can use to promote offers and deals. TOP CRITIC TAB I want a tab that will show the names of the people who have left the most reviews each month and those people who have the most followers. SOCIAL NETWORK I want the end users to be able to build a following based on their reviews. Users can follow other critics and Venues so when any new reviews are left by critics they follow or details are added by a venue they follow, this would appear on a 'news feed' when they log in. PROFILE PAGE/DASHBOARD I would like end users to be able to add a little information about themselves, again to help them build a following. EVENTS CALENDAR I want a calendar in place on a venues page so they can add details of upcoming events. BOOKINGS OPTION I want a bookings system in place. An end user can book a table, round of golf, haircut etc through our site. I am thinking something simple so a notification goes to the venue regarding the booking who will then need to contact the customer to confirm. I only want this available with a discount in place so the end user would need to receive a notification regarding the booking complete with a discount code. Hoping you will have a better idea of how this would best work.
