I can provide that the categories of the website demands. In response, I already have the plans to established in adding within the site through effective referral of advertisers shares through my internet research providing all info within your website. Meaning even though it is not me who originally advertise the things they wanted the world to know, I'll help them by advertising their company or business opportunities through your website without owning the rights as my own product. Although I can also advertise as my own benefits as well.
For example: ( If someone is selling a condominium through other website, i"ll copy that information without putting my name as the owner of the information. Meaning who ever advertises it to other website i'll still acknowledge who did that by putting the complete information with regards to advertisement of such business. Still I use the copyright since I never routed my name for them to contact me for any transaction of business if it is not my work to benefit from.
Since the very goal of your site is to populate all categories, then that's how I'm going to do that other than putting my own advertisements.. Because, base on my knowledge, freedom of advertisement means you are always free to share what information you got from other website that you wanted to help and spread the good news in terms of opportunities. In general, helping others is my top most priority even though if they don't recognize me or whoever help advertise it.)
