the higher I get, the lower my apparent altitude.
You might want to look at this website to get a simple understanding on what it takes to make a rocket get to a given altitude.

This website was written by an Eagle Scout Project by Randy Culp several years ago, and is a very well written example of simple approach to the math involved in rocketry.
The video above is of a professional sounding rocket on a ballistic flight into space. It is a similar profile to the early suborbital Mercury rocket flights with a duration of ~15 minutes. Projects on this scale cost several hundred thousand dollars.......
Unless you build the jet engine

If you can build a jet engine, you have the skills and tools to do a lot of this work yourself. It's probably only a MS degree, 5-10 years work experience at Rolls-Royce or GE, and a million or so dollars worth of tools...
It seems like the answer would be to use a jet to take it as high as it can, then dump it like a first stage and go up on rocket power, rather than taking jet oxidizer with you. I'd still buy the jet, though.
Those were just some random numbers a picked. But let's say this, something under 6 foot, and something under 8" in diameter.

Is there a altitude where you can see the black of space, but your still in earths atmosphere?
Edit: Just like the picture in the thumbnail of the video. Is there any height that would make it appear your that high? [video=youtube;JakicLZgN-o]https://www.youtube.com/watch?v=JakicLZgN-o[/video]

This is the commercial version of the CSXT rocket. https://www.upaerospace.com/SpaceLoft-Launch-Vehicle.htmlIdk about that, but I think a 6" three stage fitted with high performance motors (which would be maybe a P or a Q motor) and with an optimized shape could get up to 300,000 ft or maybe even higher (by comparison, the CXST went to 380,000 ft). I'm not too sure about this though I just did it out of the top of my head.
However, I don't think you could get a single staged rocket (I'm assuming that's the kind of rocket that you're talking about) 6 ft tall and under 8" in diameter to go to space, simply because it doesn't have enough firepower. The CSXT rocket was 10" in diameter and 21 ft long. The edge of space is 62 miles and the rocket went 72 miles high, which is 10 miles (or 52000 ft) over the boundary. By comparison the CSXT rocket is 3.5 times longer than the rocket and 4" wider. Plus, you would also have to focus on aerodynamic heating, since chances are the rocket will be going mach 5+ so you would have to put alot of insulation on it which would add alot of weight.
Anyway, I've provided a link with some information about the CSXT program, the page is pretty interesting and it gives some specs on the size of the rocket as well as its performance.

And finally, if you want to design rockets of your own, i would suggest the openrocket program, its very easy to use and can also be a helpful tool if you're designing rockets.

Hope this information helps.
