Cost of customer acquisition will depend a lot on what type of course you're looking to sell and your target audience. No one will be able to give you a straight up answer here. If you're able to provide more details, I could give some more nuanced advice :)

I'm going to make 2 assumptions in my reply 1. You're selling these to companies 2. These are rather expensive systems. Basically for such a situation, what you have right now is a first mover advantage. That basically means you have the opportunity to gain quick traction and find early adopters for your systems. If you act fast enough and manage to get companies to buy them from you, this gives you a huge advantage on your competitors. Why? This is because you have the opportunity to forge close relationships with customers and get testimonials. In the future, your competitors might be able to beat you pricewise, but that is never a substitute for trust in your company and the relationships you've been able to forge. So I would suggest spending a lot of time on 2 things 1. Creating a holistic experience for the customer from the installation of the software to the deployment. You want to be there at every step of the way when needed. If necessary, set it up for them, do some free repairs(If it doesn't cost you much). At this point you're building the relationship between you and your customers so going the extra mile counts. 2. You also want to start getting some form of testimonial to build trust and confidence in your product. This is important because word-of-mouth is more influential than advertising when selling a product. Without further information, this is all that I can come up with for now. If you're keen, I could discuss more specific strategies with you for your business and cover key actionable steps you could take to accelerate your growth and sales. :)

Before you consider selling your patented product, here are some questions you should consider. 1. Do I have a viable market? 2. Do I have sales/orders that show this demand 3. What sort of competitive advantage do I explicitly have over my competitors. It's important to get as much leverage as possible over whoever you plan to sell your product too. The best way to do this is to get hard data you can use to back up your claims and to find clear distinct competitive advantages which will cement a strong market position for years to come. If you have any further questions, drop me a message and I'll be more than happy to answer them :)

Hi, I just wanted to add on to what David Favor mentioned in his answer. It's a good step to first hire a credit cleaning company to clean up your credit. However, it's also advisable to maintain or increase your credit score for an extended period before opening this ice rink. This gives you some leverage when negotiating your payment structure with the bank. It'll also allow you some more time to put together more money so that you can afford to take a lower loan with lower interest. If you have any further questions, feel free to drop me a message. :)
