It's building and selling solar panels.
I know how to build them at a cost of no more than 275 each and sell wholesale at 475 each or retail at 700 each plus install fee-the typical retail charge from other companies is 995 for up to 40 percent interested in company or repay completely out of profit and allow investor to keep 10 for life.
Amount need is from $15,000 to $45,000 depending on what you are interested in.
