it seems that your best bet is going to be OPM..other people`s money..you say you have a biz plan, great! do you feel it is rock solid? Imagine this- if you were presented with this business plan and you had $10k making small amounts of money in a CD account, would you lend it to that person that to start the discount grocery store? if not, then figure out why and go from there. OPM is definitely going to be the way for you!
The "business planning" forum is intended to be used for questions - rather than a "full" review of the plan.
If you want someone to read your plan and give comments , I`d start with your local SCORE location. They might offer that as a free service.
If you want a full review there are several companies that offer such a service - for a modest price.
While it is true you will likely need OPM, it is unlikely that you will be able to raise 25k from any investors. You are much more likely to raise the capital as a part of a private debt solution. In this instance a private note-holder may provide you the funds for a piece of equity and structure repayment terms. In many cases you will have to make quarterly or monthly payments and you may pay a larger than normal interest rate, but the timeline will be much shorter. In addition, you really need to provide more info on your business to really get a determination of your options as my first question would be how you will get operations underway with such a small investment.
