Can you guarantee my site will be listed in all the search engines? ?

No, and no reputable company should make these guarantees! 
The only web sites that should be in the search engines are those that have an audience online.
Search engine results can take 2-12 weeks depending on the search engine.
If a clients audience is not online, or there is very little, we explore other means of promoting them within their industry to reach their business goals and achieve their return on investment.
