So I have a startup with my friend as programmers and I have two things I can tell you.
If you can afford it, my partner and I are willing to sit down and hash over details with you. That being said, developing SaaS usually takes a very long time and thus becomes very expensive. But I do think we can talk and see if we can reach an agreement seeing as how we've worked with European companies before. 3000 euros translates to around <$4000 (just ballpark guessing). This probably isn't enough to build a full and complete SaaS, unless you have a small one. It would take having more details.
That being said, as a technical startup with experience working and meeting with start up entrepeneurs...I have to agree with /u/newbusox . The ones who worry about every line of code, who worries that SOMEBODY might hear the idea and then your whole project would be meaningless, usually displays this by making us sign rigorous NDAs before willing to sit down, stresses about the speed of which it is developed and deployed and involving as few people as possible...these guys are the ones that tend not to make it far at all. Let me make this clear. If your idea is good, you need passion and work to get it there. Not secrecy. In fact, secrecy will serve to be a detriment to your success. I guarantee this to you. newbusox is absolutely correct. Nowadays, we won't even meet with someone who says something like "I'm afraid my idea will be stolen." What you should be more worried about is execution, because that is what guarantees success. If your idea will solve problems in a way that is currently not being solved, then having lines of code be re-used or people talking about your idea will not hurt it at all. And I don't think you understand the whole "lines re-used by programmers" bit. This happens no matter what, simply because an algorithm becomes part of a programmer's brain on how to solve problems. I will be honest, if you came to me with this pitch for your idea I would tell you I was interested but would not put much stock in hearing from you again, or your idea taking off. The idea is the easy part, and most likely there are already those out there with the same idea. Execution is the hard part, and not everybody has it in them to execute.
