Hi Jamie, in answer to your questions:
1) Vantage has a built in .csv importer as you can see from the
Vantage admin demo. This will allow you to import listings via a .csv file (which you can create in excel).
2) Sorry, I'm not entirely sure what you're asking here? The search is built into the theme to help people find the actual listings on the site. Could you please clarify further what you mean?
3) This could depend on how comprehensive you want the "wanted" part of your site to be? For example, you could potentially install another one of our themes,
ClassiPress in a subdirectory of your site. If you put the "Wanted" link in the Vantage menu, it would take the customer to the other location for relevant listings so that they are separate from the Vantage business listings.
e.g.
yourdomain.com <== Your Vantage installation
yourdomain.com/wanted <== Your ClassiPress installation
Otherwise, you could just use a category within Vantage specifically for this purpose, however these listings would appear with normal business listings. That's just a couple of ideas anyway.
4) There is a featured ads option available in Vantage, for which you can set the price and duration of these ads. The settings can be seen in the
Vantage admin demo here.
5) This depends on how you have set up the "Wanted" section of your site, if you're using Vantage then the listings will appear with other business listings.
6) If your listings are free then you should definitely consider moderating listings before they are published if this is an issue.
I hope this information helps. Thanks :)
