Gift basket businesses are extremely competitive. Most are worked from home to keep the overhead costs low. If you are thinking of a brick and mortar shop your expenses will be sky high. And aiming for a spa like atmosphere will be that much more expensive. Giving away free drinks and snacks? Yet more expenses.

You would need to stock plenty of inventory and a large variety to handle your walk in customers. Again, expensive.

Write up your business plan so you can list all your expenses (rent, utilities, payroll, racking, shelving, lighting, furniture, decor, pos system, advertising, inventory, supplies, taxes,...) and your funding needs. Write up your marketing plans and study your competition. What initially sounds fun and exciting can become unfeasable in reality.

Try to scale down your plan if you find it is not doable. I offer lots of ideas for gift basket businesses at my site:
