We're a collective of makers and hackers, not a job shop. Now, we can probably help you figure out how to build an X, or you may find one of our members willing to do the work for a price.
Consult Equipment or perhaps Projects. If you don't see what you're looking for there, try asking on the mailing list- perhaps someone on it has an X, or knows where you can find one available for use.
We have open-to-the-public hours on Tuesday evenings if you want to visit, and occasionally on Saturday afternoons. Consult our mailing list- we usually announce special hours there in advance. Members have 24/7 access.
Sure, however, those under 18 must have a special waiver on file (beyond the one for yourself), and you must accompany your child(ren) in the space at all times.
Most of us have other jobs during the day, and doing something like that would be difficult to arrange.
