Don't count on that. Unless you have an algorithmic-based product your idea can't be "secured". This business plan protects you only from the copy of the exact same product, so, if someone alter this a little, you can't do anything. What is the best thing to do? Start it! By the time you have mockups, go out and test them, take feedback from potential target group, keep metrics of your protype. You don't necessarily need developer or designer to do this, take your validation. After that you can go to talks with funds in a much better position. Build-Measure-Learn. Hope this helps. :)
