One thing to remember is that there are always people out there who have seen and done it before so try and get advice of someone who has been through it all already. Its not easy to find a business coach or advice and its almost certain they are not going to offer all their time for nothing. Some may even take a small share of your company to guide you through the processes.
A small group could even possibly be a community found on the internet who are experts in the field you are looking for advice in. These websites often have forums that anyone can join and ask for advice, suggestions and loads more. All this for free so take advantage of people who want to help.
