Hi,
First of all, well done for all the amazing things that you've already done. This in itself is already a great achievement.
You are correct about the processes that you need to do and if I understand your question, you want to know how you can recruit the relevant professional with a limited (or not) budget.
The most common method is the use of equity (shares/stock). some professional, if they believe in the potential of the business, are willing to either work only for equity, or for a combination of a reduced fee and equity. As to how much equity, this depends on the potential of the business, the value of the service provided and other criteria.
If you're interested, I can connect you with a professional who can help with the sales process, and I can help with the business and legal side. I would need to hear more details about the business and industry - if you're interested and have an investor's deck or exec' summary, you're welcome to send it.
Good luck
