Other shops that I know of are not accepting requests at the moment but just in case you will need more in the future, here:

The very best shop of all time:
http://www.asianfanfics.com/story/view/2984/poster-request-shop-comedy-drama-graphics-poster-request-romance-postershop
but it is closed at the moment due to A LOT of requests. Just stay subscribed so that you could request from them the moment the shop opens again.

for other graphic needs like profile photos, etc. (not posters), go here: http://www.asianfanfics.com/story/view/140112/e-n-r-e-v-e-r-i-e-graphic-request-shop-taking-request-graphic-graphics-request-layouts-requests-layout-profile

angst and horror, go here: http://www.asianfanfics.com/story/view/142288/bitter-monstrosity-graphic-shop-angst-graphic-horror-request-posterrequestshop

I'm trying to make a poster too.

AFFers usually request posters from graphic shops. Browse here: http://www.asianfanfics.com/browse/tag/poster

Be sure to check out the posters they made and the shops rules before submitting a request ^0^
