The actual amount will depend on your needs and goals. Starting a home network marketing career is ridiculously cheap compared to any other form of a home office. If you wish, you can buy individual products of your choice. There are no registration or membership fees. You don't have to buy a lot of equipment as all you need is a phone and workspace to get started; a computer is useful for online shopping. There may be additional costs: your business cards, the purchase of company brochures, training documents, DVDs, etc.
