I need some customization and will like to know if any one can help with it Multi Vendor plugin from http://dev.wcvendors.com/vendors

I need some customization for Multi-vendor plugin from [login to view URL] 1. Related products plugin; when viewing products the related products are store owner products visit [login to view URL] for details. But i want a second line of related products that will display other stores products. 2. Vendor paid plan plugin; Right now the plugin does not have paid plan every vendor just register and upload products but i want to have several paid plans like silver, gold, Diamond etc. If a vendor is on diamond for example his products will be the first sets of products on the home page and category pages, and Gold vendor products next to it, so the higher the plan the more preference and more dominant the vendor products will be. It will be monthly paid plan and once a vendor pay we can activate his account or if payment is made online the account is automatically upgraded to the paid plan. 3. Advert spaces plugin, i want to create some adverts spaces that we can insert ads codes from Google, [login to view URL] etc. 4. E commerce expert plugin; We want a plugin like job plugin where freelancer can sign up and display their skill sets related to their e commerce experience and vendors can go there and employ them to manage their store on their behalf which means the expert being employed will be granted expert privileges to be able to perform certain functions on behalf of the vendor, like upload products, manage store, customize the store etc. The plugin should be able to monitor the expert and keep the records or log of whatever he did so the vendor will be able to view all expert activities on vendor account and keep record on expert work on the vendor account showing how many hours an expert spent on vendor account and the exact job expert did, vendor should be able to view work log of expert to determine how many hour spent and the exact jobs done. Multi-vendor admin should be able to view log too and once vendor approve the task of an expert Multi-vendor admin can pay him. Which means that before a vendor will employ an expert he/she must deposit some funds on his account on Multi-vendor to enable Multi-vendor admin pay expert at the end of the task or month. It can be a proper job plugin where expert will apply and vendores can screen and make selection, it should include educational background, skills acquired, certification, previous job, previous jobs on Multi-vendor and current vendor he is working with Note: I want price per task listed above. 2. I want to know what it will cost if it is developed as a full plugin that other wordpress woocormmerce user can use. 3. I want to know the cost if it is just a customization that will work on our multi-vendor store alone.
