I typically fly solo, so have done this a few times...

I use one of those folding step ladders as a rest for the mast while stepping it (definitely helps in getting the mast started up). I untie one of the jibsheets from the traveller, and tie it off to the forestay. Once the mast is raised, I just cleat in the jibsheet, and it holds the mast in place, while I go up front and pin it in. Raise the jib, releasing the tension on the halyard, and untie the jibsheet. Then retie the jibsheet to the traveller, and off you go...(after raising the sails, of course)

This way, it doesnt need any additional lines, poles, wires or such.
