Business Planning 101
To begin, if you are a Christian, I suggest you pray and ask for guidance. If you are from a background where God's only communication is the bible then this part may prove difficult. The Bible in my opinion is the source of our discernment and litmus test for heavens communication, but it does not replace first person relationship with its author. The role of the Holy Spirit is critical to your understanding the nature of God from the inside out. A lot of what is done "in the name of Christ" sometimes has little if in come cases anything to do with God. We like to feel religious and hope that others see us that way. It makes us feel good about ourselves but it can be destructive to having a relationship with Christ. All to say you need to make sure this is God's vision not your own fantasy. There is a very big difference.
A business plan is a methodology of organizing your thoughts into a format that will allow you to turn your ideas into a realistic picture. It is a step by step process that can utilize the services of various professionals including, graphic designers, accountants, architects, and contractors. It is not something that happens over night. A well thought out business plan is a thing of beauty that often takes months of analysis.
Local resources
There are numerous blogs, internet sources, and software packages available. you will need a working knowledge of Word and Excel to put together your narratives and spread sheets. Make sure you are comfortable with what ever format you choose to use.
If you are fortunate to live near a local university with a business department, they often hold seminars or business fairs to help upstart entrepreneurs flesh out their ideas. If they are available then make sure you compensate them well for helping you. If you have God beside you, he will want to bless those who help put together His program. Don't use people. God pays his own way.
