Getting a website domain purchased would be a great start. Once you have a website domain, that will probably correspond to the name of your business, so you can then go ahead and file your paperwork to establish your corporation, LLC, LLP, etc. A good next step is to develop a business plan. Many web-based start-ups do not require financing due to the low start-up costs, so your business plan could be more for operational purposes. In the event you are seeking funding, your business plan will need to be much more detailed. Seek Scott`s advice and use the resources available through SuN! Good luck
