There's over 7,000 3D printing services, some incredibly cheap, some more expensive. I'll tend to use it if my machines are down or if I need something made in a material I don't have the capability to print with (ASA for example -- damn prolific PTFE-based extrusion tubes...).
For material suggestions, ABS is always a solid choice, hard to go wrong there. PETG is also good but is such a giant PITA to work with really, it's stringy and gets everywhere and is very tempermental at times, even the good stuff. ASA is great for outdoors use but is hard to find a print shop that can print with it given the required extrusion temperatures being above what most printers can print with (again, prolific PTFE-based extrusion tubes are why). If you need flexible, TPU works well and has plentiful real-world examples (flexible phone cases are usually injection-molded TPU).
Whatever you do, avoid PLA like the plague. It's great for indoors-only prints or fitment prototypes (I do a lot of this), but it's abysmal handling of heat and biodegradable nature mean its only suitable purpose outdoors is flower pots (thanks to Maker's Muse for that idea). Generally seen as an obsolete type of filament, but don't tell my stash that, it's going to be a while before it's gone!
And hey, if anyone needs help with anything relating to 3D modeling, printing, design, I'll help in whatever way I can. I'm all for this, I'll do whatever I can pro bono to a reasonable extent. I obviously can't give away $700 worth of filament in a print, but I'm not going to try and sell you a turd for that much either.
