I had never developed a strategic business plan, an employee handbook, a hiring process, a minority certification process or an operations manual.
The questions you have asked here are good ones. They require long and well-researched answers and that is the purpose of doing a business plan. The Denver Metro Small Business Development Center has both short (Business Plan Basics) and long (NxLevel) classes which can give you what you need to know in order to do this. In addition, we have several consultants who specialize in Internet based businesses and planning. The consulting is free, unlimited and confidential. Just go to this web site to register for consulting and/or classes: www.denversbdc.org.
Regarding your questions about financing, those are the kinds of things that would also be answered by doing the business plan. I can tell you that lenders are very reluctant to loan to startup software companies and that usually that kind of funding is found through investors.
I am not sure what a “temporary license from Denver” would be. I have never heard of that before. But I can tell you that it will not be good in Chicago. Every governmental unit has its own requirements for registering a business even within the same State. Normally if you maintain a physical presence within that location (such as an office), you must be separately licensed within that town, city, state, etc.
Secondly, if you are also an owner of the business, it cannot be a sole proprietorship. Sole means sole, i.e., only one owner. You can choose to be a traditional partnership, a multi-member LLC or a corporation of one type or another. The SBDC has regular classes on Startup Basics which can give you the information needed to make that decision. Or you can schedule a meeting with one of our consultants for that advice. But it is an important decision and you should make it knowing all the facts.
Finally, yes, you will have to pay taxes in both cities (states) where you earn income. If your residence is in Colorado, the State will give you a credit on your return for the taxes paid in Illinois. You can get the appropriate tax return forms online at the department of revenue web sites for each state. Or you can have a professional do your taxes for you and the business.
It sounds as if you done almost everything you need to do for the move to Colorado. But, yes, there are some things you need to do for the City of Denver if your base of operations is going to be inside city limits.
Although Denver does require the registration of certain
specific businesses, photography is not one of those businesses.
However, there are some taxing requirements you will have to register
for. One of these is the Occupational Privilege Tax. This is required of
all employers with the city, including those who are self-employed. The
tax is $4.00 per month.
Secondly, Denver collects its own sales taxes. Although services are
not generally subject to sales tax, if you sell anything that is
delivered on electronic media or any other tangible products (such as a
photo album), you must register for and collect sales tax.
You can get help with both of these by contacting the Denver Business Assistance Center at 201 West Colfax Avenue or by calling 720-913-1715.
Finally, Colorado has a complex sales tax system which is determined by “point of delivery.” There are many levels of sales tax collected by many different entities around the State. If you are doing business in other locations, you may be subject to one or more local sales taxes. Each one of these entities should be checked individually to determine whether or not you are liable for collecting the sales tax.
