Experience with hiring to make mods?

[Overland]

I Love KSP, I love the community we have..but more importantly I love land trains

Ive got big ideas that now have reached the limits of stock parts

 

mod parts that I use work great..but look wrong or unsuited for thier function..

All this has me in need of 3d models

Regretably though despite originally knowing my way around gmax some 10 years ago..life..time and work have eroded my skills to near non existant

So! With all that established...

The ideal of hiring someone from say the unity asset store occured to me..

The KSP side of things i can do myself or learn to do.. 

Generally the idea is to contract x modeler to model x parts for a mod id happily release for free

Does anyone have any experience in hiring outside help for projects youd like to give feedback on? 

Im looking for someone to model a kerbalised version of a smaller aircraft tow tractor... Or rather a shunter, land train locomotive and a few wagons in modular fashion (with IVA) eg
