You came up with the perfect plan and now are ready to implement it. This is already the most difficult thing you have done. Then comes the time to obtain money and establish the separation between your business and private life.
Nevertheless, you have no business experience, which means you have no business credit score either. Consequently, it would be difficult to obtain a classic business card. Then, you are left with your personal credit score.
There is an option of obtaining a business credit card for someone with average credit score. It is called Capital One Spark Classic. It is the best card for those who want to create their business in the future but first have to improve their credit history.
Then the next card for you is American Express Blue Business Cash. It gives two percent of cash back for your expenditures in certain categories. However, to obtain it, you will need a better personal score, and this card looks more like a business one.
But you should not apply for all five cards at once as this will lower your credit score. Apply for one card and use it to make only small purchases and pay the whole amount at the end of the month.
This is the basis of your future empire. Treat the card as a tool anad not as your free source of money.
