ROKU Channel Development using RSS delivery

I am developing ROKU channels as well as for Amazon and other IPTV OTT boxes. I have rss feeds set up and need the channel development from there. You will compile the files needed to submit to the ROKU channel Store and be approved by ROKU. Insertion of advertising VAST coding is also needed. You will have experience in doing this and can also handle submitting channels on a weekly basis as we are launching many channels Show me your experience and previous works in this area. I can supply all graphics need to complete the look of the channel
