Try SBA website, and seek out available grants and loans that are for start up businesses. If you’re a woman or minority, there is special funding .
You must do your research relating to the market/business you plan to enter, and write an outstanding business plan to present to prospective lenders. That is about the single most important step towards receiving loans to fund your project.
