Here is what I offer any players that want custom cards made:
$50 covers costs for 50 cards (plus shipping) and includes all research for stats/career on back (which I will communicate to assure correct facts). I do all the design and work 100% for free. Cards are top quality, glossy UV coating exactly like today's cards. I do ask that player signs about 20-25 cards for me to use as "collectible inserts" to entice customers to buy packs. I DO NOT sell the signed cards; they are only randomly put in packs. These extra cards are printed at my cost. I will provide return pre-paid shipping and even a sharpie to make everything as simple as can be. Extra cards can easily be ordered at a reduced rate.
What I need:
A high-quality good resolution photo or two, preferably a privately-owned one or gifted one so we don't piss off a photographer who owns rights haha. Since these aren't for your resale and you are probably getting them more for nostalgia, there never is really an issue.
