Artist to Create Realistic but Fictional Technical Drawings

I am looking to hire an artist/designer to create a set of realistic- looking technical drawings for a fictional missile. I have made a loose sketch for reference to the best of my ability to communicate the general idea, though liberties are welcome. Like the sketch indicates, I'm seeking a set of three drawings; a cutaway view of the internal components with labels, an image of the outside appearance without labels, and a close-up view of the warhead with a few simple labels. Though it's a fictional object, it's based on mostly real components for realism and reference. The general idea is that it's an afterburning turboramjet missile powered by a modified Pratt & Whitney J-58 engine. It has an adjustable aerospike for a nose, followed by a compressor turbine. Compressed air is routed around the warhead and through the JP-7 fuel tanks for cooling. It's then released into the combustion chamber where it's mixed with fuel from a ring of fuel nozzles and ignited inside burner cans. Behind the main fuel tank is an array of smaller tanks for storing triethylborane. Additional fuel is stored in the wings. The warhead is the most fictional aspect of the design and is where the most artistic liberty and interpretation is welcome. In principle, it's a small stone sphere bearing a geometric pattern with two shaped charges placed on either side. The sphere is meant to be some sort of ancient, possibly non-human reactor, squandered as the driver for a pseudo-nuclear reaction. The shaped charges are blocks of explosive with a hollowed-out cone to direct the blast. They are operated by a fire-&-control circuit as shown in the sketch. Salguerre, the fictional manufacturer, has their logo on the rearward side of the missile in the outside drawing. I've included a .PNG of their logo for convenience. In addition to the Salguerre logo, on the outside view drawing there should be a damask/paisley pattern wrapped around the nose. I've also included a .PNG of a sample of the kind of pattern I mean, use of that .PNG is perfectly acceptable as well. The drawings themselves should be plain black and white, delivered preferably as .PNGs. Dimension lines should be included if possible, the dimensions themselves do not truly matter though I've included some semi-realistic examples for reference in the sketch. Even little sketch lines to give it a pencil-and-paper kind of look, whatever works. The sketch also has two different versions of tail fins, I was experimenting with looks, I leave the shape up to your discretion. Forgive my long-windedness, thank you for your time.
