What's 1st. Giving contract or getting investors?

[Mordy Chaimovitz]

Rookie question

I am in contract for my first deal. All is well for now. 

I would like to start looking for my next deal however I know I will need OPM to invest in the down payment. Which leaves me in a quandary.  

Can i give a letter of intent to a seller if i have not yet secured investors for a downpayment? and if not,  how can I get investors to participate in a deal that I am not in contract for?

to summarize my question, what comes first, finding investors or finding a deal?

Although a few people have said i can contact them with investment opportunities, this lack of clarity is preventing me from really looking at deals seriously 

thank you all for your time
