gun doctor on the go

i am a disabled veteran that loves guns... cleaning guns, fixing guns, restoring guns, anything to do with guns. my wife and i go to the gun shows and we always here people asking. can you install this if i buy it?  yes we can. bring your gun we will take it back to our shop and in two to tree weeks or longer we can ship it to your local FFL delear for pick up. so you have to pay for the part. the work. the shipping and the FFL pick up... on top of that. after the wake of harvey in texas. every one is going to help with watter food housing fixing houses and bildings fixing cars and trucks. taking care of anamles and people... but i see no one help out our firearms...once i have this up and going...i will follow the gun shows as well as if i am ever needed. i will go help out the firearms that are in destress as well...so that i can repay what you give me. i will give back to the guns that need help when a desaster comes knocking... thank you... 
i will be buying a trailer so as that the shope is moble. i will buy equipment that i do not have as yet. i will bild the inside of the trailer shop to fit all that is needed for this and stock it as needed...i plan for all the work to be on a tip/donation basses.
