in OPT you can alwasy work for multiple employer. Everification is only required to renew your OPT. So my suggestion is to work in same company and search for some Consultancy and register yourself so that you can use their name while renewing the OPT. If renew process requires pay cheques, the you can pay tax to those consultancies and they will generate the payroll for you. This is just a work around in the worst case. Good Luck.
