the deal you got is pretty much a scam but you might have no other choices but to accept it at first, if you have no capital and no experience.
Once you've got a business set up, which might take up to 2/3 years if you ever get successful, you'll have to renegotiate and probably leave this firm.
Make sure to keep a copy of your initial contract and read every pages of it.
Look for the lenght of the contract, the money you'll have to give them if you want to leave before your contract is up, the non compete stuff, make sure you are not liable to any debit balance in your account.
Good luck
