Be very, very, very careful with any proposals you receive regarding working from home. DO NOT part with any money until you have thoroughly researched every aspect of the proposition and have solid evidence that it is right for you and that it will work. That means having a proper business plan and conducting a thorough and comprehensive SWOT analysis.
Too many people lose money, their livelihoods, and their friends and family through risky ventures. If you cannot afford to lose the money if it does not work out for you, then steer clear.
