Wall tent service

[OL_JR]

So long story short I would like to get a roof jack sewn into my wall tent and abandon the side exit. The biggest and imho only advantage to the side exit is the ease of putting a tarp over the tent. My plan is to have a roof jack installed on the tent and tarp. Airdrie canvas wants 450 bucks to do the job and I feel like shopping around may be in order to say the least. That's basically half the price of the tent I have.

Looking for other places to do some shopping around. If the quoted price is competitive I'll bite the bullet and try it myself.
