I am a Professional Engineer, Civil, and also hold certification from American Welding Society as SCWI (senior welding inspector), along with NACE and SSPC tickets..
My day job is maintaining the massive suspension bridges that connect Manhattan Island, Long Island, Staten Island to the rest of the US.
While the powerpack you are choosing is small compared to what I usually see, I think you are really limiting yourself just being a welder.. Package all your skills so you can travel.. We have seen you bodywork, and mechanical, as well as amazing carpentry.. bring it all... not just one narrow slice of your talents..
I do design and consulting as well as fabrication with for my friends business.... This is all on a barter agreement. Ill cut bend and weld tubing and I get zero dollars.. what I do get is lift time and use of tools that I don't own i.e. dyno, alignment rack etc.
I think now is a time to sell all your skills.
