Not irrelevant at all. Some developers are strictly freeware like me so would never get involved with a payware project. There is also the legal aspect. You might not appreciate that many commonly used freeware programs & utilities are either not allowed to be used for commercial purposes or require a licence from the author to do so. The latter also applies to proprietary software like FSDS & Photoshop* where the commercial version of the application should be used by anyone intending to profit from its use. This is plainly stated in the EULA but I often wonder how many commercial FS developers actually take any notice of these conditions.
It would also be a good idea to know exactly what you intend doing before advertising for people to help you do it.
*PS. It's unclear how this applies to gMax.
FSDS and gmax can be used for commercial projects without needing an extra, commercial license.
Some programs, like the academic versions of 3DSMax, Microsoft Office, etc. are for personal, academic use, and would need upgrading to a "regular" version.
Either way, you do'nt have to say that the proposed project is specifically " incredibly detailed model of a Singapore Airlines Airbus A340-600"
Usually, stating that the project is a "modern military transport" or "a series of GA aircraft" is better descriptive.
Remember, you're "selling" yourself at this point, and while "I need designers" may seem enough for you, for people to respond (and I'm not saying no one wouldn't respond on that basis) it also seems too much like the "for a good time, call MAry" signs.
Basically, what I would like to see, is enough information for *me* to evaluate so I can make a first determination if I think my own skills are up to par/likiing for the project.
