Cheryle,
Welcome to the forum. There are plenty of business around High Wycombe using AutoCAD and Inventor, we just moved from Marlow to Kingsmead Business Park in High Wycombe. If you have free time I suggest you find the closest company and apply for an internship. Everyone needs some help and willing to train in return.
In the last place I've worked we had a student for every engineer. I have sent you an email so check gmail.
Hello Cheryle,
I’m presuming that the course that you are on is a city and guilds course? Whatever it is I would suggest that you complete that before you start anything else so that you are not getting pulled around in all directions.
There are loads of Inventor tutorials within inventor and also out there (Google) and loads of videos on YouTube.
If you get stuck with anything then this forum is one of the best to ask for help. I’m not sure that local help would be any good. There are a lot more voices on this forum.
Regards
Warren
