Hi there!
I'm a UK-based, professional 3D modelling and design expert, specialising in Autodesk Fusion 360.
I'd love to be a part of SmallSpark Space System's project - I've had a look at the UKSA animation video that you linked, and I will be more than capable of creating a 3D model of equally high complexity and quality. Depending on wether you need all internal components modelled, or just the outer shell, the completion of the model may take anywhere from around 3-14 days. Either way, with your sketches and design specs provided, I imagine this should be a fairly straight forward project for us.
I actually have experience with a very similar style of project, with a Canadian Aerospace company that hired me through Freelancer (https://www.freelancer.com/projects/rendering/Vito-Hub/). The project aim was to create a highly accurate 3D model based on the designer's 2D AutoCAD drawings and specification, to be used for a number of purposes: visual content to aid with the design patent, 3D printable component files for prototyping, and 3D models for use in animation and simulation. Unfortunately, I am not able to disclose any visual examples of the work done, but I hope that you are able to gauge my level of ability with this style of project!
Please also note that I have placed a 5% Expert Guarantee deposit on my bid.
I'd really appreciate if you could send me a message so that we can discuss your project in further detail.
I look forward to hearing from you!
James
