Have you ever thought of starting your own business offline? Maybe you thought about owning your own retail shop or pizza shop or something like that. I know I have thought of owning a pizza shop, especially after learning how much you can make from running one. But then the reality sets in – there are startup costs, employees to pay, rent to make every month. It just plain costs too much to get started with an offline business.So you probably turned your attention to starting an online business to make money or you looked into some other option to make extra cash. If you are worried about the startup costs involved with starting an online business, I can tell you straight away that the costs are minimal. In fact, they are less than the cost of a cheap dinner for two.In short it is possible to start a six-figure online business from scratch in just a few days time. You do not need a lot of skills and thanks to the power of pre-made free software and social media sites; you can start an online business for little to nothing down.Domain Name – You will want to create a virtual brand around your online business and your branding efforts start with your domain name. Head over to NameCheap.com and find an available domain name for your product and website. The cost is less than $10 per domain.Website – You can start with Word Press or Blogger, which are both free blogging platforms. I recommend that you start with a blog for your website and invest a little money every month to host a Word Press blog. Word Press makes it real easy to add onto your blog to make it look like a professional website.Hosting – To host your website or WordPress blog, you only have to spend $5 a month at HostGator.com. I think you will agree that the cost is more than manageable.Products – You can create a product from a Word document, publish it for free with a free online PDF creator like FreePDFConvert.com and you now have a product to sell…that cost you nothing except time to create.Shopping Cart – No, not that kind of shopping cart. An online shopping cart is the software or service that will accept credit cards for you when you sell your products to customers. Clickbank.com charges $49.95 as a one-time fee, plus a percentage of each sale made.You can also use PayPal.com which is free (except for per sale processing charges), but they do not have active affiliates like Clickbank.com who will see your products and instantly be able to promote your product. Clickbank.com has over 150,000 affiliates. It is well worth the one-time investment to have access to that many affiliates.Autoresponder – You are going to want to capture the names and email addresses of your website visitors. By offering a free report or email course, you can get people to give you this vital information so you can follow-up with them and remind them to purchase your product, as well as provide them with great content. Cost for Aweber.com, one of the leading autoresponder services is $19.95 a month.Congratulations! You have your very own online business for less than $100, a fraction of what it would cost to build an offline business. All told you have spent roughly $85 to create a product, build a website and be able to accept credit cards.And remember, if you do not have $100 to invest in your online business right now, you can start by setting up a blog at Blogger.com for nothing at all and you can create your product to sell for free through PayPal, also free to join. Where else can you start a business for nothing down? Nowhere!Invest When You Can Afford to Invest – Now I am all for starting small and not spending a lot of money until you prove out that your market is willing to pay you for your products, but there will come a time when you should invest in your business.When you make your first sale or get your site up, you should look into investing in graphics for your website and your product covers. Graphics will definitely help your products and website look more professional and grab the attention of your prospects.So your strategy is to start small with a free Word Press or Blogger blog and then build your online business from there, adding products and other content over the months.
