Post an Offer! This is the best way to kick off your PPH experience and to get some short-term work. An Offer is like an express Job. Once you have a Buyer you agree on a delivery date and start working.
A buyer may even purchase your offer to see if you are right for a longer term Job. There is no commitment from either party to continue after the work for the first offer has been completed.
You can list more than one offer covering all the types of work you can do for buyers. Remember though, not to over-commit and pause your offers if you have a lot of work on.
You can, of course, still complete your Profile, search for projects and make Proposals.
