Hi,
request should be posted
here ( check the top one sticky )
Changing the speed of a gif can be
easily done here:
https://ezgif.com/maker ( upload you stuff, then change the speed ).
About getting a loop, first glance it looks possible.
And if you're willing to post a request don't forget to post how much you're willing to spend ( help a lot people who may attempt ) !
Gl.
