TLDR: Two young friends winging the whole process of starting a private jet company and have tons of questions
Some background: My friend and I are in the midst of starting a private aviation company. He has 2 years at an executive level while I completed bachelors.

Currently, we made up a list of every potential investor we know (wealthy friends, millionaires in the industry that my friend knows, old family friends). We have an edge on the current market in operating a small number of planes at low cost leading to maximum profit. We wrote out all the initial expenses and the expenses for scaling and the plan step by step on the process we plan to take and how much money we will need for each step on the way. (We can’t be exact because there are certain things we can’t check until we have money- Are investors expecting every number to be exact?)
We plan to only hold one type of aircraft supermid size (perhaps CL30’s) and aim to provide maximum quality for that market. To purchase/operate the company it would require an investment in the single digit millions. The plan is to buy an existing company, so we don’t have to deal with acquiring an Air Carrier Certificate (they tend to take multiple years of back and forth with the FAA). We have certain connections to people with existing planes (that are not super close with us but would be open to hearing us on the phone) and they might be willing to sign management agreements so we can use their planes to sell flights. The industry standard is coming up with an agreement where operational costs are split proportionally to revenue. The company we end up buying will also connect us with current aircraft owners in that company and the chance to resign them.

Questions:
We plan to show the investor 5 companies that we liked based on certain methods and dig deeper into each of them after some funding. Is that a common thing? Should we put in our own savings into hiring professionals to review the companies? Are we expected to cover analysis costs? Investors will obviously want to analyze the company themselves, is wasting our money necessary?

What is the standard in terms of how much equity we need to give up per investment? We are smart/hard working people that are pretty much selling ourselves with confidence that we know enough, have enough experience, and planned enough to succeed. If our expected income is roughly 200k per month.
Are crowdfunding sites worth looking into?

We both did not study business at school, so our ‘business plan’ google doc doesn’t feel like a legitimate business plan. It feels like we just threw a bunch of numbers on a paper- were not sure what a business plan is supposed to look like and what kind of format these investors are expecting.
We have no experience approaching someone to ask for money. We have avoided calling anyone so that we don’t burn any bridges before learning as much as possible about the industry. Now that the time is nearing, what’s the best way of contacting these people? I assume it’s different for each person but let’s say we are calling one of the aircraft owners. What are they expecting from the 2 minutes initial pitch? What is the standard way to go about this?

Our attitude right now is that we will succeed and anyone who chooses to invest is lucky to work with us and hop on our train. Is this a good/bad attitude?
In what order do you recommend we approach our contacts? And is it a good idea to approach all in the same month? (We were thinking if we get multiple offers we want them at the same time to compare)
What are expected operational lawyer fees? It seems like the only time ill need a lawyer is to write up employment contracts. Is there anything else I’m missing, assuming I don’t get sued?
Any good ideas for company names :)
Apologies for the long post, thanks for reading!
