There are many modelers in the world to whom you can get in contact with through internet and they can work with you without physically meeting with you. It is better to hire an experienced person who come under your requirements on internet rather than a person who lives near you and have no experience in this filed. You can get any kind of models whether you need people 3D models for games or sofa 3D models for furniture business. There are some important things which you need to know and see these things below:
You need to talk to the modeler in detail and see if he understood your project or not. Even if you are talking to them on internet, you can ask for a video call so that you both will know each other and talk one to one like you are talking to a person sitting right next to you.
You need to talk about all the important parts of your project and especially the time signed to that. It is necessary that you also about it before hiring a modeler especially when you need the models urgently because if failed to provide the models within time then you may have to suffer from monetary loss. Sometimes people who are working these kind of projects are also working on a full time job too which gives them little time to complete other projects so they may not be able to provide you projects when you need them on urgent basis.
You need to see their work history in this field and ask them different questions about it so that you will know about their understanding level in this field. You need to know what they will do if the work hard on a project and it will not come out as they expected after working hard for so long. Did they give up on that or they work again to correct their mistakes or did they start the project all over again. This is very important to know about because anytime a model can be failed to provide the best results. After getting answers according to your expectations only then you can hire them otherwise you need to think again about it. Giving up should never be an option, they need courage to get results.
