Do you have extensive connections in production? Do you own, or know someone who owns, the equipment and skills necessary to produce your series? If not, do you have the money to hire/rent that equipment and skillset?
Assuming you have a really GREAT web series written - say ten to twelve five to ten minute episodes. They are just FANTASTIC!. You have terrific actors, skilled at acting for the camera - not the stage - you have connections with people who are at least decent at camera work, costuming, lighting, location management, catering etc. etc. -
Have you ever produced a short film? Was it made 'right'? Exactly the way you wanted it, without sacrificing on acting, sets, costuming, camera, sound, lights?
Because film is probably the MOST collaborative art form there is - you're ALWAYS 'sacrificing' something - time, money, patience - to get the thing done.
My suggestion is to write one episode - and try and produce it. If it's as fun and fullfilling and great as you think it should be - make the rest.
