If you need more cash, set up a corporation and go look for a line of credit. If that doesnt work, find a partner. Go find someone you work with or know and present them with a business plan, go 50-50 on everything and use have them buy in to the business by matching the funds you have outstanding with your lead networks.
Just ideas. If you're making money, really making money, then it shouldn't be difficult to find money.
This is completely wrong. When you setup a corporation, it'll cost you a little cash ( which it sounds like you don't have ), in addition, any credit you try to get in the companies name will be approved based on your credit/social security/name (ie. if you personally have a problem getting more credit now, your company will get jack shit).
[Note: If you have excellent credit then do go corporate, you indeed can get a much larger line of credit than you otherwise would]
You'll be hard pressed to find a bank that doesn't pierce the corporate veil and require the SSN and personal guarantee of the officers of the corporation. (sucks, true though).
And if you find someone dumb enough to partner with you based on your track record (at least on WF), please let us know how you did it.
BTW, not trying to give you a hard time, drives me nuts when people set all these false hope expectations.
Your best option is weekly wires and slowly scale, as you continue to generate revenue, you'll eventually have enough to go big. If you really are earning 20% weekly ROI, even with a spend of only $2000 per week compounding, you'll have $8.5k in 8 weeks ! If you do this, on weekly wires, you now will have 8k per week to invest .... and in another 8 weeks from that point, you'll hit 34k, assuming you maintain that ROI and continue to reinvest the returns weekly.
My guess is, this won't happen, fluctuations in traffic and conversions could easily have you losing your ass if you aren't careful one week (bringing invest able amount down significantly). In addition to that, some traffic sources/categories simply have a hard upper limit on what you'll be able to spend to get traffic, without increasing your bids and adversely affecting your margins).
Basically, don't rush head first into a brick wall, you can still scale over a short period of time without risking losing your ass in the process.
