Professionally, we use the services for protoypage via the Initial Company (initial.fr), they have an office in the 80. Now regarding the final goal, for a functional part like a neck that will really be used, I don't think the 3D part is the solution. 1) The cost, even if the costs are reasonable, it may be as expensive as the original part. 2) Solidity, even if the parts can be solid, they are far from being able to hold the required function where the constraints are still important.
3) the "Fun" or the pleasure of having a 3D part, in this case yes, but not for this application, but rather a more decorative object... Whatever the type of 3D printing, nothing could reasonably meet this function. There is still the injected or machined protoype, but there it is more expensive than the complete vacuum cleaner.
Like @mwalti, I have often had pieces made at Initial (it's at the other end of France for me...): very good quality, price seems correct and speed.
Now for your needs, choose a PVC wire deposition solution rather than stereolithography, it is more resistant to wear and holds better on low thickness, according to my experience... Pay attention to accuracy!
Otherwise, I think that supermarket chains should have entered this market (Auchan I think). I don't know if it's all over France.
For my part, we use 3D printing at least once a week.
Over time, we have selected 3 suppliers that we systematically put in competition since the prices vary from imple to double depending on the object to be printed!
Sculpted to begin with is nice because of its online quote system. On the other hand, the relationship is a little less effective.
Otherwise, we use ARKK Protomold and AXIS Prototyping which are very pro-oriented.
So for a personal usgae, you might as well consult Sculpto and quite frankly, they are very good, the deadlines are very correct and the prints very good.
Only the prices vary.
Good luck
EDIT: I don't particularly agree with @mwalti.
As Tomalan says, the choice of material is essential but a good glass bead finish, and from a mechanical point of view, I would be curious to compare with some injected materials...
And the original quality is also very good (the white plastic from Sculptéo = Duraform from the others).
It's still sintering but mechanically, it's quite enough.
I myself am the owner of a 3D printer contacted me privately. After for the price it all depends on what you just ask for printing and sending or modeling in addition.
Kind regards

I recommend MG2 which manufactures with stratasys and Fortus machines. So if you need parts close to PE, PC, PEI or PPS with tolerance to +/-0.2mm, so technical parts close to thermoplastics, I recommend.
I have them made between 10 and 200 pcs/month and never had any problems.
To follow up on this question I had this part made not different from the owner of the printer. wanting to buy one I thought great test !!!!
So the first one to answer was @bastien, with a prussa. Nice achievement but weakness on the resistance between cycles=> the part broke in a circular way.
then Sclulteo fine grain polished parts superb but we don't know what type of machine
Finally I contacted Ultimaker directly..... after information, discussion by email etc.. The after-sales service offered to make the part for testing free of charge
The piece received undeburred is of an inpressuring quality. I will contact them again to get as much information as possible on the manufacturing process because at 2000€ the end (+ tax etc...) I have the impression that it is a very good machine.
