Help with iRules and URI redirection

Hello everyone. I am looking for help with irule design to perform the following: remove "services" from uri and forward traffic to a specific pool as following 

http://dev.api.company.com/services/nameofservice1
http://dev.api.company.com/services/nameofservice2
http://dev.api.company.com/services/nameofservice3
http://dev.api.company.com/services/nameofservice4
http://dev.api.company.com/services/nameofservice5

pool1_8888
pool2_8889
pool3_8890
pool4_8891
pool5_8892

dev.api.company.com/services/nameofservice1 ==> dev.api.company.com/nameofservice1 ==> pool1_8888
dev.api.company.com/services/nameofservice2 ==> dev.api.company.com/nameofservice2 ==> pool2_8889
dev.api.company.com/services/nameofservice3 ==> dev.api.company.com/nameofservice3 ==> pool3_8890
dev.api.company.com/services/nameofservice4 ==> dev.api.company.com/nameofservice4 ==> pool4_8891
dev.api.company.com/services/nameofservice5 ==> dev.api.company.com/nameofservice5 ==> pool5_8892

Any help and/or assistance will be greatly appreciated. Thank you all.

    Sorry, forgot to add.. I need to perform the port translation. The browser should not see theother ports except of 80. Thank you again.

    This should provide a rough idea. Create a datagroup: CLASS_URI_POOL

    /services/nameofservice1:=pool1_8888
/services/nameofservice2:=pool2_8889
/services/nameofservice3:=pool3_8890
/services/nameofservice4:=pool4_8891
/services/nameofservice5:=pool5_8892

when HTTP_REQUEST {
set POOL [class match -value $URI contains CLASS_URI_POOL]
if { $POOL eq "" } {
HTTP::uri [string map {/services/ /} [HTTP::uri]]
pool $POOL
}
}
