Hello, We are looking to modify 3 or 4 modules inside of vTiger. If you have experience in vTiger please let us know. These modifications are not to hard, but you do need to know about the modules inside. One thing we need to do is take the invoice module and have it fetch the AMOUNT from the Database and pass it through a Paypal API so they can pay that invoice via the email we send out. That is really the hardest part of what we need done, the other stuff is really small compared to that. If you have experience please message us how much an hour you work for and how much experience you have with vTiger.
