I doubt if it will be enough. Let's say your rent is 350 - 550k/year, you only have 450k left and you still have to make shelves, buy work tools like tables, chairs, notebooks etc. Not enough left to buy products.
Depends on several factors especially rent of facility and how many products you want to start with. Without mentioning an amount, figure out the rent, arrange with a distributor on how much you can pay to lift multiple products and you are half way into the business. Best of luck.
Usually start with research. Where are your suppliers? Which location is suitable and affordable for me? Where/who are my customers? Answer these questions and you will get a clearer idea where to start from.
Obviously, this requires some work. Some products and conducive for some locations, some are not. Consider being a level 3 or 4 member so we can work on this request for you.
