ACH Website Upgrade

I have a wordpress theme from adforest, i want to use a directory plugin on the theme. Basically i want the plugin functionality but the look and feel of the website must not be changed. Some custom styling would need to be used to achieve this. The plugin is Sabai Directory and i need it to function as follows. User can come to home page of website, use the search box to search for any business listed on my website. The home page must also have featured listings whicy are listings businesses would pay a little extra for, to be visible on home page. Remember i want the site to look just as it is, with the plugin’s functionality. The search results page, i want it to look just as is now, but display the information that would be captured when a user submits a business listing (via form) The business details page should look just as it does now, just display the information captured by the “add business” form. (Some adjustments to exactly what is displayed would need to be made) Any business owner should be able to submit their business, and they do not need to create an account. However it would be mandatory for them to have an email address in order to submit their business listing. On the form to submit their listing, there should be 3 options to choose from (packages). When the add business form is filled out and submitted, they should be taken to the payments page, once payment is completed, they should be redirected to a page displaying how their listing would look, with a notification above saying that the listing is pending admin approval. On the search results page it must display as the theme currently displays results. The site must look just like the theme displays now, but with the functionality of the sabai plugin. So the plugin must be seamless. And again, i want the site to look exactly like it does now [login to view URL]
