Auction , classified site creation?

Auction , classified site creation?

  
I was originally going to use Iron Speed , but since their fall, I am looking for another solution.I am looking for a system to build an auction type site with multivendor capability and advertising function and native apps for my users. Does Outsystems have this ability? I was going to go with a premade app and have it modified for the many extra features I will require, or is there a better solution for me by suggestion. 

I am not a developer at all , but I do have a pretty good understanding of databases work and are structured and how systems like Iron Speed or Alpha software works.
Unless you have a significant budget to hire some people or a company to develop this with you, I strongly suggest finding an existing application like those you mentioned that will be good enough for now.   When you make your first million, then look at a custom solution.  :-)  

Obviously, Outsystems can be used for almost anything but writing one yourself will be a frustrating task for someone with limited software development skills.  

Hope this helps,
Curt
Does anyone have suggestions for someone with experience creating ecommerce auction type sites? Because what I will be requiring I think is good to start with a base system with different admin levels on the back end, but I have several features that would be exclusive to my site. I am a very experienced power seller on eBay and I have several ideas that will change the way an auction site should run that caters to the users both buyers and sellers and I know where I can definitely get users. Thanks for any input.
