getting a game company to even look at the engine.
Why would a game company look at the engine? As far as we know from your posts, you personally don't have any proven track record or good reputation within -- or even outside of -- the industry. Given it's incomplete your engine certainly isn't proven or well known.
Games companies are a business, and in the business world people generally look to minimise risk, especially when investing potentially very large amounts of money. They either use proven, capable engines (Unreal, CryEngine, etc.) created by developers with good track records (Epic, CryTek, id, etc.), or they develop their own technology in-house.
For a business to even consider your engine you would need to first complete the engine and produce at least a demo showing it's capabilities.
Given you apparently don't have the money to do this, your best bet to proceeding would probably be to seek investment so that you can hire the programmers you need to get the job done. Investors will want to see a detailed business plan and that you have a reasonable chance of success.
No games company is going to look at your incomplete and unproven engine, so if you want to proceed with it you are looking to start a business venture.
Note, 8 years IS NOT reasonable experience
8+ years of experience is a senior developer, and will be appropriately expensive. If you absolutely must have developers with that much experience then your engine is either poorly designed or isn't nearly as complete as you're suggesting. Consider that Epic Games (Unreal) has a number of positions for engine programmers. Link. Link. Link. They're only asking for 3+ years experience. If you genuinely require a developer with 8+ years of experience you're setting the bar really high, and should expect your costs to be really high as well -- expect to have to defend this requirement if you approach investors.
Honestly, I really think you might be better off simply moving to a readily available proven technology to create your own games. If your ideas are really for platform games and similar then you simply don't need a great AAA-quality engine like you're describing, and given your apparent financial situation it would be far more achievable to pull together ~$500 for Game Maker, or use the free version of Unity (or the $1,500 version), or similar rather than having to find a very expensive developer to work for you.
Unless you are able to raise the money to complete it, what you really have isn't an nearly complete engine, but a collection of completely useless code that will never see production use. Sorry if that comes across as harsh, but it's the reality of your situation.
